Hi Manish,
Try
# data set
x <- structure(list(V1 = structure(c(1L, 3L, 4L, 2L, 4L, 2L), .Label =
c("A",
"E", "X", "Z"), class = "factor"), V2 = structure(c(1L, 2L, 3L,
4L, 3L, 4L), .Label = c("B", "T", "U", "V"), class = "factor"),
V3 = structure(c(1L, 1L, 3L, 3L, 3L, 2L), .Label = c("C",
"P", "Z"), class = "factor"), V4 = structure(c(1L, 2L, 3L,
4L, 3L, 4L), .Label = c("D", "K", "M", "R"), class = "factor")), .Names
= c("V1",
"V2", "V3", "V4"), class = "data.frame", row.names = c(NA, -6L
))
# result
lapply(split(x, x$V3), "[", c(1, 2, 4))
See ?lapply, ?split and ?"[" for more information.
HTH,
