obligatory dplyr solution:
library(dplyr)
zeroes = Test %>% group_by(ID) %>% summarise(Zs=all(X==0))
- that gives you a data frame of unique ID and Zs==TRUE if that ID
has all zeroes. With that you just sum(zeroes$Zs) to get the total
number with all zeroes. Or add "%>% filter(Zs) %>% nrow()" t

Hi,
Sorry to chime in late, but here's an alternative solution, without
conditionals:

[1] TRUE

Dear All,
I am not familiar with R language well. Could you please help me interpret
these commands?:
TE = exp(sum(coef(cox)[c('aTRUE', 'bTRUE')])) - does it mean exp(coef(a
variable) + coef(b variable)) ?
DE = exp(unname(coef(cox)['aTRUE'])) - what is unname for ?
Thank you very much befo

It's not an R problem: you don't have the necessary tools installed in linux,

I have a data.frame (below) containing the two fields of "Value" and "Signal"

Do I have to create a for-loop

Do you have curl installed? RCurl just uses your external-to-R system
installation of the curl software to do its real work.

I think you need to have curl-config installed. I had a similar
problem on Ubuntu and found the program in various packages:.
$ apt-file search curl-config | grep bin
libcurl4-gnutls-dev: /usr/bin/curl-config
libcurl4-nss-dev: /usr/bin/curl-config
libcurl4-openssl-dev: /usr/bin/cu
Dear John,
R-sig-mixed-models is more suited for this kind of questions. All follow-up
mail should be posted only to that mailing list.
It seems like varIdent() by default relevels the grouping factor and that the
user cannot control this.
