I have an indexing question. I have a data set that looks like this:
b
[[1]] [1] 22 23 24 25 26
[[2]] [1] 6 7 8 9 NA
etc. from [[1]] to [[1000]]
Then I need to use the sample function to take two samples from b[[1]] to b[[1000]] each separately. I thought something like "sample(na.omit(b[[1:1000]]),2,replace=TRUE)" would work but it doesn't. Is there a way to index this properly?? Thanks,
Nathan
