How do I increase the memory for R?

Windows users may get the error that R has run out of memory.

If you have R already installed and subsequently install more RAM, you may have to reinstall R in order to take advantage of the additional capacity.

You may also set the amount of available memory manually. Close R, then right-click on your R program icon (the icon on your desktop or in your programs directory). Select ``Properties'', and then select the ``Shortcut'' tab. Look for the ``Target'' field and after the closing quotes around the location of the R executible, add

--max-mem-size=500M
as shown in the figure below. You may increase this value up to 2GB or the maximum amount of physical RAM you have installed.

239#239

If you get the error that R cannot allocate a vector of length x, close out of R and add the following line to the ``Target'' field:

--max-vsize=500M
or as appropriate.

You can always check to see how much memory R has available by typing at the R prompt

> round(memory.limit()/2^20, 2)
which gives you the amount of available memory in MB.
