I want to use rxImport function Import a csv file to xdf, the file,which have more than 25 thousand column.
With RRE, you can manage wide datasets such as this through some switches -
You can set the max-ppsize flag when starting R in order to use functions.
For example, using R directly (i.e., rgui.exe or rterm.exe), set the max-ppsize=500000 when you type R: R --max-ppsize=500000.
On Windows with the RPE, set the max-ppsize flag in the call to the RevoIDE executable: RevoIDE.exe /RCommandLine --max-ppsize=500000.
