check empty data

[shoaibali]

I am checking if my column (name) have any empty cell but getting error. any solution....???

df <- df %>% mutate(is_blank_node = which(df$Name == "", arr.ind = TRUE),1 )

Error:

Error: Problem with mutate() input is_blank_node.
x Input is_blank_name can't be recycled to size 182753.
i Input is_blank_name is which(df$Name == "", arr.ind = TRUE).
i Input is_blank_name must be size 182753 or 1, not 0.

Hello!

It is not completely clear how your code should work but you can do something like the below:

sapply(iris, is.na)

This will return a dataframe that shows you for all values if there is empty cells or not. You can then reduce those columns to single values. Is this helpful?

Let me know if this is the solution you needed

@shoaibali

df <- df %>% mutate(is_blank_node = which(df$Name == "", arr.ind = TRUE),1 )

I think your issue here is missing two different syntax (base / tidyverse)
I'm guessing the tidyverse style you would use would be

df <- df %>% mutate(is_blank_node = Name == "")

although the above assumes the character field Name would be character(0) rather than na_character_ when 'blank'
