The goal of listchr is to flatten list-columns of a data frame into strings, in order to export it to a more simple format (csv, ...).
The reverse transformation (separated string to list) can also be done.
You can install listchr from github with :
# install.packages("devtools")
devtools::install_github("py-b/listchr")Convert all list-columns of a data frame into character vectors :
library(listchr)
df <- data.frame(x = 1:2)
df$y <- list(letters[1:3], 1:2)
df$z <- list(list(3:4, 5:7), "d")
str(df)
#> 'data.frame': 2 obs. of 3 variables:
#> $ x: int 1 2
#> $ y:List of 2
#> ..$ : chr "a" "b" "c"
#> ..$ : int 1 2
#> $ z:List of 2
#> ..$ :List of 2
#> .. ..$ : int 3 4
#> .. ..$ : int 5 6 7
#> ..$ : chr "d"
df2 <- listcol_to_chr(df)
str(df2)
#> 'data.frame': 2 obs. of 3 variables:
#> $ x: int 1 2
#> $ y: chr "a;b;c" "1;2"
#> $ z: chr "3;4|5;6;7" "d"
