Easiest way to do this is to use paste     gt  paste  Today is   date     1   Today is Sat Feb 21 15 25 18 2015    paste0   would result in the following    gt  paste0  Today is   date     1   Today isSat Feb 21 15 30 46 2015    Notice there is no default seperator between the string and x  Using a space at the end of the string is a quick fix    gt  paste0  Today is    date     1   Today is Sat Feb 21 15 32 17 2015    Then combine either function with print     gt  print paste  This is   date      1   This is Sat Feb 21 15 34 23 2015    Or   gt  print paste0  This is    date      1   This is Sat Feb 21 15 34 56 2015    As other users have stated  you could also use cat

As other users said  cat   is probably the best option    krlmlr suggested using sprintf   and it s currently the third ranked answer  sprintf   is not a good idea  From R documentation      The format string is passed down the OS s sprintf function  and incorrect formats can cause the latter to crash the R process    There is no good reason to use sprintf   over cat or other options
