Hello,
I'm having trouble in using "assign(paste ..." command . I could create
several dataframes following trinomial distribution using it but it could
not be used to check their row means of the created dataframe.

For example, the following works:

probTrt=matrix(0,4,3);
probTrt;
#malf, death, normal
probTrt[1,]=c(0.064,0.119,0.817);#for Trt 1
probTrt[2,]=c(0.053,0.125,0.823);#for Trt 2
probTrt[3,]=c(0.111,0.139,0.750);#for Trt 3
probTrt[4,]=c(0.351,0.364,0.285);#for Trt 4
for (t in 4){
        assign(paste("Trt",t,sep=""),rmultinom(10, size = 5,
prob=probTrt[t,]));
    }



But the following does not work.
for (t in 4){
        assign(paste("Trt",t,sep=""),rmultinom(10, size = 5,
prob=probTrt[t,]));
        rowMeans(paste("Trt",t,sep=""));
    }


How can I use it in functions like rowMeans so that I don't have to type all
the object names? Thank you.
