How can I instruct R to left justify the text in a character column when displaying a data.table?

How can I instruct R to left justify the text in a character column when displaying a data.table?

For example, how might I instruct R to left justify column "text" in the following output so that it matches the desired output?

library(data.table)
(data1 <- data.table(text = c("AAAAAA", "B", "C"), number = c(1, 2, 3)))
#>      text number
#> 1: AAAAAA      1
#> 2:      B      2
#> 3:      C      3

Desired output:

#>    text   number
#> 1: AAAAAA      1
#> 2: B           2
#> 3: C           3
Solution

  • You could pass justify = "left" argument to print.data.table:

    print(data1,justify="left")
     text number
   <char>  <num>
1: AAAAAA      1
2: B           2
3: C           3
