hi
i have a data frame that this df have a nested list and i want to unnset this all df . when
unnest_wider() function i get an error .
how to resolve this error or you have any idea for tidy this df?
df <- tibble(
a = list(c("a", "b"), "c"),
b = list(1:2,list(c("d", "f"))),
c = c(11, 22)
)
Error in col_to_wide():
! Can't combine ..1$...1 and ..3$...1 .
What is the desired final structure here ?
it's a json file that we want to tidy it
what would it look like when its tidy ?
how will you know that you got the 'correct' result ?
the list's seperate in column's.
how many columns should there be in the result for your example ? can you say the number ?
the number of return column's is based on the list that we have. for example in b column we have two list that return two columns.
So the first row should have 5 columns, and the bottom row should have 4 columns ? Does alignment matter because data.frames have to be rectangular and 5 and 4 columns would not be...
Do the names of the columns matter or no?
df %>%
mutate(b = map(b, as.character)) %>%
unnest_wider(b)
