Description

The append() method is documented to allow (1) cbind() (column append) functionality for matrices and (2) allows strings to be appended to other strings.

However, cbind() also seems to allow strings to be appended to other strings. Since cbind() is a matrix function, this seems incorrect.

makes = "makes";
makes_sense = append(makes, "sense");
print(makes_sense);

doesnt_make = "doesn't make";
doesnt_make_sense = cbind(doesnt_make, "sense");
print(doesnt_make_sense);

output:

makes
sense
doesn't make
sense
