head(a_tibble) fails if NAs present in column names

[nathancday]

Not sure if this is expected behavior or not. However it was not the behavior in version 1.3.4, it would run without error and return the escaped NA.

library(tibble)

data(iris)
tib <- as.tibble(iris)
head(tib)

# A tibble: 6 x 5
  Sepal.Length Sepal.Width Petal.Length Petal.Width Species
         <dbl>       <dbl>        <dbl>       <dbl> <fctr>

2         4.90        3.00         1.40       0.200 setosa 
3         4.70        3.20         1.30       0.200 setosa 
4         4.60        3.10         1.50       0.200 setosa 
5         5.00        3.60         1.40       0.200 setosa 
6         5.40        3.90         1.70       0.400 setosa 


# with NAs
names(tib) <- gsub("Species", NA, names(iris))
head(tib)

Error in data.frame(id = seq_along(x), max_widths = map_int(map(x, get_widths),  :
