how about sum(!is.na(x)) ?

the following works. i don't exactly what happens here. I guess "lm"
might treat S1 and S2 as quantitative variables, not qualitative
variables.

S1 <- as.character(Data[,1])
S1 <- as.factor(S1)
S2 <- as.character(Data[,2])
S2 <- as.factor(S2)
data <- data.frame(S1=S1, S2=S2, ExM=

another function you might be interested in is cbind.

Dear R Users,
I'm using Rmpi package for paralleling computing. It's very useful.
But I have two question:
1. before running processes on slaves, all the data should be sent to
them. however, if i forget to broadcast some of the data, the master
will freeze, and I have to kill the process manuall
in order to return more multiple variables, you can put them in a list
and then return this list.
e.g.
#Function A
boot<-function(a,b,c){
mean_boot<-(a+b)/2
var_boot<-c
list(mean_boot = mean_boot, var_boot = var_boot)
}
out <- boot(1,2,3)
out
$mean_boot
[1] 1.5
$var_boot
[1] 3
