Try to do this
library('stringr')
apply(data, 1, function(x) str_c(x$columnnane,collapse=","))
where, data is you dataframe and columnname is the column containing list.
edited answer
out = do.call(rbind, lapply(data, function(x) str_c(x,collapse=", ")))
where data is your list object
if the list is stored inside a dataframe then pass the column in place of the data above like this
out = do.call(rbind, lapply(data$columnname, function(x) str_c(x,collapse=", ")))
it will give you this. I hope this is what you are looking for!
