Try this:
for (i in 1990:2009) {
varName = paste("pci", i, collapse = "")
assign(varName, log(get(varName))
}

I believe that ``sep= " '' is needed here rather than collapse.
Try:
paste("junk",42,collapse="")
You get
[1] "junk 42"
with a space in it. Here paste is using the default value of sep,
namely " ",
and is not using collapse at all, since there is nothing to collapse (the
value is a scalar to start with).
Whereas
paste("junk",42,sep="")
gives
[1] "junk42"
which is what is wanted.
