Hello,

I would recommend you to use the package "colbycol" in CRAN, which
reads files column by column and lets you select which ones to load
into memory, etc.

It can be better suited to you than the regular read functions.

As a disclaimer: I am the author of the"colbycol" package, which was
motivated by problems similar to this one. I would love to hear how it
fares and to get feedback from users so that I can improve it.

Best regards,
