data frame names in sequence
...ve been stuck with this problem for a whole afternoon. It's silly but
totally pissed me off. I have a set of data frames with names in a sequence:
df_1, df_2, df_3, ..., df_20. Now I want to access each data frame (read or
write) in a for loop, in a way something like this:
for (i in 1:20) {
df_i <- ######
length(which(df_i[,7]==1))
######
}
I tried paste or cat ("df_", i, sep=""). But neither way works. Your help is
highly appreciated!! Thanks in advance!
