flextable requires R >= 4.1.0

[trekonom]

As documented in this SO post flextable 0.9.6 might break with an error on R < 4.1.0. The reason is most likely that in some places apply is called with simplify=FALSE, e.g.

flextable/R/compose.R

Line 202 in b03d310

}, simplify = FALSE)

which was introduced in R 4.1.0 (see the New Features section on R 4.1.0 here).

I was able to reproduce the issue using flextable 0.9.6 and the rocker:tidyverse:4.0.3 docker image:

library(flextable)
#> Warning: package 'flextable' was built under R version 4.0.5
z <- summarizor(
  x = CO2[-c(1, 4)],
  by = "Treatment",
  overall_label = "Overall"
)

ft_1 <- as_flextable(z, separate_with = "variable")
#> Error in FUN(newX[, i], ...): unused argument (simplify = FALSE)

ft_1
#> Error in eval(expr, envir, enclos): object 'ft_1' not found

thanks @trekonom I will try to fix very soon

[eli-daniels]

The package passes all CMD tests by just removing the only two occurrences of simplify = FALSE in compose.R in the labelisor() function. But whether it is being tested already, I'm not sure.

[davidgohel]

it should be fixed now
