When I do this library iplotsI get the following error. I do have JDK installed on my pc. The error is telling you that there is no entry in your Registry that tells R where Java is located on your machine.

Either your registry is corrupt, but more likely you haven't installed Java. If that doesn't work, you can start looking at exactly where R is looking for your Registry entries. The function that rJava uses to find Java is in the rJava Within that function there is a subfunction called find.

I copy the contents here:. Copy and paste this into your R window, and then run it find. If that isn't listed, then it is missing from your registry. You could also manually set the directory of your Java location by setting it before loading the library:.

It resolved this error but created another issue. The solution in above link resolves this issue without creating additional issues.

That typically needs to be run after an update of the system Java installation, as suggested here. Learn more. How can I install rJava for use with 64bit R on a 64 bit Windows computer?

Difference between 32-bit and 64-bit version

Thierry Onkelinx. Difference between bit and bit version. Dear all, I'm a bit puzzled by the difference in an object when created in R bit and R bit. Consider the code below. My goal is the calculate a SHA1 hash on the coef test to track if the coefficients of test have changed. I'd like to get the same hash on a bit and bit system.

A simple hack would be to calculate the hash on round coef test Is that a good or bad idea? Duncan Murdoch Re: Difference between bit and bit version.

I tried to create a dummy dataset with the same structure to replicate the problem with the need of sending my dataset. However all of them gave identical results between bit and bit.

Is it correct to infer that tiny difference between bit and bit are possible but have a low probability of occurring? Using 20 digits gives identical results, 21 digits gives non identical results. Best regards, ir. This is FAQ 7. Differences are rare, but it's hard to assign a probability to them. In many cases the 32 bit calculations are more accurate, because they tend to use more 80 bit extended precision intermediate values, but that is not guaranteed. Free forum by Nabble.

Edit this page.You can report issue about the content on this page here Want to share your content on R-bloggers? R itself moved to a 64 bit memory model some time ago, but still has only 32 bit integers.

This is going to get more and more awkward going forward.

What is R doing to work around this limitation? Such integers can only count up to about 2 billion. This range is in fact ridiculously small and unworkable. Some examples:. Note we are not talking about big-data issues which are addressed in R with tools like ff, data. Fortunately, when working with data you really want to do things like aggregate, select, partition, and compute derived columns. With the right primitives you can and should perform all of these efficiently without ever referring to explicit row indices.

Now R actually dodged these bullets, but without introducing a proper 64 bit integer type. First a lot of people think R has a 64 bit integer type.

But feast your eyes on the following R code:. What the R designers did to delay paying the price of having only 32 bit integers was to allow doubles to be used as array indices and as the return value for length! Take a look at the following R code:. It looks like this was one of the big changes in moving from R2. However, it feels dirty. In a more perfect world the above code would throw an error. This puts R in league with languages that force everything to be represented in way too few base-types JavascriptTCLand Perl.

However, I still would much prefer the introduction of a proper 64 bit integer type. Of course Java is in a much worse position going forward than R. In much better shape is Python which has been working on unifying ints and longs since PEP and uses only 64 bit integers in Python 3 just a matter of moving people from Python 2 to Python 3.

Where we are told that the integer is in the range to in hindsight we can see R is printing as if the data were floating point and then, adding insult to injury, it is not signaling its use of four significant figures by having the decency to switch into scientific notation. In fact it becomes a bit of a bother to even check if a floating point number represents an integer. The true value is seen as follows:. But, that or whatever IEEE math library function actually does this is hard to feel very good about.

However every data scientist should read this paper to understand some of the issues of general numeric representation and manipulation! Our advice is to first try representing 64 bit integers as strings. For functions like read. Thank you to Joseph Rickert and Nina Zumel for helpful comments on earlier drafts of this article.

However, if you're on Windows 10, Windows 8, Windows 7, or Windows Vista, the chance that you're running a bit version goes up considerably. Of course, this isn't something you want to take a guess at.

Knowing if your copy of Windows is bit or bit becomes very important when installing device drivers for your hardware and choosing between certain kinds of software. One quick way to tell if you're running a bit or bit version of Windows is by looking at information about your operating system installation in Control Panel.

However, the specific steps involved depend a lot on which operating system you're using. Another quick and simple way to check if you're running a bit or bit version of Windows is to check the "Program Files" folder. There's more on that at the very bottom of this page.

Open the Control Panel. You can check your Windows system type much faster from the Power User Menubut it's probably speedier that way only if you're using a keyboard or mouse. With that menu open, select System and then skip to Step 4. Choose System and Security within Control Panel. If so, select System and then skip to Step 4. Choose System. System command from Run or Command Prompt. Find the System area, located under the large Windows logo.

Within there, next to System typeit will say either bit Operating System or bit Operating System. The second bit of information, either xbased processor or xbased processorindicates the hardware architecture. It's possible to install a bit edition of Windows on either an x86 or x64 based system, but a bit edition can only be installed on x64 hardware.

Choose System and Security. Select System. Locate the System area below the oversized Windows logo, and look for System type among the other statistics about your computer.

There is a junction for York's northern bypass Awhich was built in the late s, and on the left is Pike Hills golf club and Askham Bogs nature reserve where the road is followed by NCN The road then crosses the River Ouse.

The University is now much closer to the bypass due to its new Heslington East campus, and the Grimston Bar Park and Ride is accessed from the same junction. The York bypass terminates at the Hopgrove Roundabout [4] named after the nearby Hopgrove pub in Stockton-on-the-Forest with the A former route and A near Forest Park golf club. This roundabout has lengthy queues at peak time, and is scheduled to eventually become a grade separated junction.

Going east in the direction of Scarborough, it passes the Highwayman cafe on the left, and the Vertigrow Garden Centre, close to where the former York to Beverley Line crossed. At the turn-off for Sand Hutton is an agricultural research laboratory Food and Environment Research Agencywhere the road enters the district of Ryedale and re-enters North Yorkshire.

It passes Claxton Hall and a right turn for Claxtonand left turn for Flaxton.
