Re: [R] diff doesnot work

diff() does not work on data.frames so you need to give it a column from the data.frame, as a vector. diff(data.frame(P=c(1,2,3,5,7,11,13,17))$P) [1] 1 1 2 2 4 2 4 You get different errors for multi- and single-column data.frames > diff(data.frame(P=c(1,2,3,5,7,11,13,17),

Re: [R] how to interpret t.test output

Hi Somayya, When you perform a t-test on two sets of numeric values, the answer you get tells you how likely it is that those two sets of numbers came from the same distribution. What most people are interested in is whether the means of those two distributions are different. Let's see, you seem

Using R is a grate advantage, thanks for your work. Using regex under R 3.1.1, Debian 8.6 jessy works fine. str_detect("16-03-08", "[:digit:]{2}") [1] TRUE str_detect("16-03-08", "[0-9]{2}") [1] TRUE runing the same code under R 3.3.2 backport, Debian 8.6 jessy gives a different result. This is

Perhaps someone could, but: 1) It is normal on public Internet mailing lists and forums to simply ask the actual question and let people respond if they know the answer, rather than asking for permission to ask. 2) You should read the Posting Guide for this mailing list... your question does

Re: [R] Beginner needs help with R

I think it is important to point out that whenever R treats a number as a numeric (integer or double) it loses any base 10 concept of "leading zero" in that internal representation, so in this expression seq2 <- paste0("DQ", sprintf("%06d", seq(060054, 060060))) the arguments to seq have

Two methods, among others: seq1 <- paste("DQ", sprintf("%0*d", 6, seq(060054, 060060)), sep = "") or seq1 <- paste("DQ", formatC(seq(060054, 060060), dig = 5, flag = 0), sep = "") Hth, Adrian On Mon, Feb 6, 2017 at 3:50 AM, Nabila Arbi wrote: > Dear R-Help Team!

You need the leading zeros, and 'numerics' just give the number without leading zeros. You can use 'sprintf' for create a character string with the leading zeros: > # this is using 'numeric' and drops leading zeros > > seq1 <- paste("DQ", seq(060054, 060060), sep = "") > seq1 [1] "DQ60054"

Re: [R] Beginner needs help with R

Hi Nabila, This is because you ask to create a sequence with seq(), which does not make much sense with non numeric data. That's why R trims the 0. One alternative would be: seq2 <- paste("DQ0", seq(60054, 60060), sep = "") Would that work for you? HTH, Ivan -- Ivan Calandra, PhD MONREPOS
