#>  [1] -0.4 -1.6 0.2  -1.1 -0.1 -0.7 1.4  -0.8 -1.5 1.1 
formattable(rnorm(10), format = "f",
  flag="+", digits = 1)
#>  [1] -1.3 -1.8 -0.1 +0.7 -1.1 +0.3 +0.5 +0.8 +1.3 -0.8
formattable(1:10,
  postproc = function(str, x) paste0(str, "px"))
#>  [1] 1px  2px  3px  4px  5px  6px  7px  8px  9px  10px
formattable(1:10,
  postproc = function(str, x)
    paste(str, ifelse(x <= 1, "unit", "units")))
