I got advice here that I didn't understand! Can I ask to explain me the meaning
of this procedure: first get the structure, and then assign it back. For what?
Thanks! (Great thanks to Moderator/Admin!)
You should learn to post in plain text and use dput to present your data
structures. At your console do this
So this is what you do to display your data-frame in a plain text way.
dput(treat)
# and this will appear. Copy it to your plain-text message:
structure(list(ID = 1:5, start = c(0L, 0L, 0L, 0L, 0L), stop = c(66L,
18L, 43L, 47L, 26L), censor = c(0L, 0L, 1L, 1L, 0L), sex = c(2L,
1L, 2L, 2L, 1L), age = c(1L, 2L, 3L, 3L, 4L), stage = c(3L, 4L,
3L, NA, 3L), treatment = c(1L, 2L, 1L, 2L, NA)), .Names = c("ID",
"start", "stop", "censor", "sex", "age", "stage", "treatment"
), class = "data.frame", row.names = c("1", "2", "3", "4", "5"
)):
Then this is what we, the readers, do to read in your data-frame so we
are sure we have exactly the same as you had.
Then we can just do this:
treat <- structure(list(ID = 1:5, start = c(0L, 0L, 0L, 0L, 0L), stop = c(66L,
18L, 43L, 47L, 26L), censor = c(0L, 0L, 1L, 1L, 0L), sex = c(2L,
1L, 2L, 2L, 1L), age = c(1L, 2L, 3L, 3L, 4L), stage = c(3L, 4L,
3L, NA, 3L), treatment = c(1L, 2L, 1L, 2L, NA)), .Names = c("ID",
"start", "stop", "censor", "sex", "age", "stage", "treatment"
), class = "data.frame", row.names = c("1", "2", "3", "4", "5"
))
If you carry on posting in HTML it is possible that your e-mails will
get scrambled so it would be best to post in plain text. It does not
seem to have had a bad effect this time.
