listchr

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.

Installation

You can install listchr from github with :

# install.packages("devtools")
devtools::install_github("py-b/listchr")

Example

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)

df2 <- listcol_to_chr(df)
str(df2)
