%c% is just a short operator implementation for paste(x, y, separator="").

x %c% y

Arguments

x

first string

y

second string, which will be pasted behind the first one.

Value

returns the concatenation as string.

Details

R-Core does not consider it a good idea to use + as an operator not being commutative. So we use c here.
See the discussion: https://stat.ethz.ch/pipermail/r-devel/2006-August/039013.html
and https://stackoverflow.com/questions/1319698/why-doesnt-operate-on-characters-in-r?lq=1

Still the paste syntax seems sometimes clumsy in daily life and so %c% might spare some keys.
