Increase Memory in R
Sometimes R users get the out-of-memory error; to solve that, we can increase the memory in R. This tutorial demonstrates how to increase the memory in R.
There are two methods to increase the memory in R; one is manual, and the other is a method.
Increase Memory Manually in R
Windows users mostly get out-of-memory errors. We can increase the memory of R from the properties of the R program or app.
Follow the steps below if you are using Windows.
-
Right-click on the R program icon from the desktop or the program directory and go to
Properties.
-
Go to the
Shortcuttab and find theTargetfield.
-
Add the following line into the
Targetfield.--max-mem-size=1000M -
The code above will allocate 1000 MB of memory to the R program; the maximum can be the memory up to the memory of R.
-
Finally, click
OK, and you are good to go. -
There might be an error that R cannot allocate the vector of length. Then add the following line to the
Targetfield and clickOK.--max-vsize=1000M
Increase Memory by the memory.limit() Method in R
memory.limit() can allocate memory to an R program. It takes one parameter size in MBs.
Let’s try an example.
memory.limit(size=1000)
The code above will allocate the 1000 MB memory to the R program.
