However, I can't save the result

Sorry... no love. Double backslashes doesn't cut it. Double backslashes prints
nothing. Single backslashes removes the first character of my command. But no
single backslash!
paste("\parbox[b]{3cm}{", test, "}", fill=TRUE)
Gives me:
[1] arbox[b]{3cm}{ foo }
[2] arbox[b]{3cm}{ bar }
and
paste("\\parbox[b]{3cm}{", test, "}", fill=TRUE)
Gives me:
[1] parbox[b]{3cm}{ foo }
[2] parbox[b]{3cm}{ bar }
No backslash.
