I have created this data frame to help illustrate my problem. id<-c(rep(1,5),rep(2,5),rep(3,5),rep(4,5),rep(5,5)) x<-rep((seq(1:5)),5) y<-c(0, 0.1, 0.5, 0.4, 0.2, 0, 0.1, 0.5, 0.4, 0.12, 0, 0.1, 0.5, 0.55, 0.2, 0, 0.1, 0.5, 0.3, 0.2, 0, 0.1, 0.6, 0.4, 0.1) d1<-cbind(id,x,y) I would like to delete all rows where id=4, however, when I tried the command  d2=d1[-c(id==4),] and looked

Hello useRs: Does anyone have thoughts on the lifecycle of older releases of R? I know that currently the 2.8.x and 2.9.x releases seem to be actively "supported" on the mailing lists, but what about older releases, say 2.4.x?

Hello, I want to use seq with multiple from values and am getting unexpected (to me) behavior. I'm wondering if this behavior is intentional or not. > seq(2, by=3, length.out=4) [1] 2 5 8 11 > seq(3, by=3, length.out=4) [1] 3 6 9 12 Now if I want the combined sequence, I thought I could pass in c(2,3), and I get: > seq(c(2,3), by=3, length.out=8) [1] 2 6 8 12 14 18 20 24
