[R] selection part of "subset"

[Christof Kluß]

Hi

I want to do something like

a <- c(10,20,15,43,76,41,25,46)
tab <- data.frame(a)

name <- "a"

for (v in unique(tab[[name]])) {
  r <- subset(tab, name==v)   # this does not work
  ...
}

i.e. a "string" on the left side of the select expression (subset). How
could I solve this?

thx
Christof
