You can read a file using pipes like this:

d = read.table( pipe( 'cat data.txt' ), header = T )

There's also no reason to confine this to just ssh commands, you could also do something like this:

d = read.table( pipe( 'cat *.txt' ) )

See the R Data Import/Export page for more information, specifically the Connections section.
