Hello,
I have a csv file with many variables, both characters and integers.
I would like to load it on R and do some operations on integer
variables, the problem is that R loads the entire dataset
considering all variables as characters, instead I would like that R
makes the distinction between the two types, because there are too
many variables to do:
x1<-as.integer(x1)
x2<-as.integer(x2)
x3<-as.integer(x3)
...
I tried to specify read.table(... stringsAsFactors=FALSE) but it
doesn't work.
You need to use colClasses
