Is there a way to print text and variable contents on the same line? For example,

wd <- getwd()
print("Current working dir: ", wd)

I couldn't find anything about the syntax that would allow me to do this.

You can use paste with print

print(paste0("Current working dir: ", wd))

or cat

cat("Current working dir: ", wd)

Print string and variable contents on the same line in R, You can use the paste function from the base package to print strings and variable contents on the same line, as follows: wd <- getwd().

{glue} offers much better string interpolation, see my other answer. Also, as Dainis rightfully mentions, sprintf() is not without problems.

There's also sprintf():

@agstudy's answer is the more suitable here

Print values on R console or file using cat() or print(), also returns the argument so it can be assigned. The “digits” argument specify the number of digits that should be displayed. Numbers are rounded off to that digits. In this tutorial we look at functions to print values on R console or file.. The values are normally printed on the console since that is the default sink, but you can specify that the output be sent to a file by opening up a sink to the file. we will see an example of it in this tutorial.

Easiest way to do this is to use paste()

> paste("Today is", date())
[1] "Today is Sat Feb 21 15:25:18 2015"

paste0() would result in the following:

> 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:

> paste0("Today is ", date())
[1] "Today is Sat Feb 21 15:32:17 2015"

Then combine either function with print()

> print(paste("This is", date()))
[1] "This is Sat Feb 21 15:34:23 2015"


> print(paste0("This is ", date()))
[1] "This is Sat Feb 21 15:34:56 2015"

The {glue} package offers string interpolation. In the example, {wd} is substituted with the contents of the variable. Complex expressions are also supported.


wd <- getwd()
glue("Current working dir: {wd}")
#> Current working dir: /tmp/RtmpteMv88/reprex46156826ee8c

  • You probably want sep = '' or you'll get an extra space.
  • Using cat() I get a NULL at the end :(
  • @ragesz i only get null on the end if you put the cat inside of a print like: print(cat("test", var)) which should be cat("test", var)
  • Another nice option! This is very similar to other scripting languages and very convenient if you have a text where you want to implement multiple variables. Thanks!
  • by far the most convenient option, especially if you're composing a function argument. with paste it quickly becomes an unreadable mess.
  • Note that sprintf does not print, it just formats the string. Something like print(sprintf(...)) is necessary inside scripts.
