?merge
Here is what you would do:
x1 <- read.table('/tmp/list1.txt', header=TRUE, sep='\t', as.is=TRUE)
x2 <- read.table('/tmp/list2.txt', header=TRUE, sep='\t', as.is=TRUE)
combined <- merge(x1, x2, by.x="Probe.Id", by.y="Probe.ID")
Unfortunately your data did not have any IDs in common between the two
files.
