[R] Export cols to single csv files

[B77S]

just use indexing.
without doing it all for you...

df <- structure(list(AA = c(0.3, 0.1, 0.6), BB = c(0.9, 0.4, 0.2), 
    CC = c(1, 0.8, 0.6), DD = c(0.7, 0.5, 0.5)), .Names = c("AA", 
"BB", "CC", "DD"), class = "data.frame", row.names = c(NA, -3L
))

write.csv(df[,1], paste(colnames(df[1]), "csv", sep="."))
