[R] Help Help with sampling

[Alex99]

Hi everyone,

I have a dataset(named "Mydata") which includes 4 different variables named;
s1,s2,s3,s4 .Each variable(symptom) has 14 patients.
I need to use random sampling to make, 5 different samples from my data with
5 patients in each sample. i.e. using all 4 variables I need to make 5
different samples by changing patients(with 5 patients in each sample).


   X8 X9 X10 X102 X110 X177 X283 X284 X286 X292 X297 X306 X308 X314
s1  0  1   0    0    0    1    0    0    0    0    0    0    0    0
s2  0  0   0    0    1    0    0    0    0    0    0    0    1    0
s3  0  1   0    0    0    0    0    0    0    0    0    0    1    0
s4  1  0   0    0    1    0    0    0    0    1    0    0    0    0


I used this code:

temp=list(NULL)
for(i in 1:5) {temp[i]<-sample(Mydata,5, replace=F)} show(temp)

but I get the following error:
"number of items to replace is not a multiple of replacement length"

any idea why I get this eeror message and how can I fix it?
Thanks a lot.
