Hi,
Could you please help me in solving the following error message:
Error in `[.data.frame`(mytestdata, fp_temp == 1) :
undefined columns selected
when I use scan instead on read.table, I reicieve this message:
Error in names(ret2) <- rowns :
'names' attribute [172] must be the same length as the vector [152]
Many thanks,
Nancy
