Pass normal arguments of global functions in Purrr map functions.

[Nick1991]

Example 1.
df_list <- map(filelist, read_excel) # WORKS!!!!
df_list <- map(filelist,read_excel(col_names = F)) #WHY NO WORK???

Example 2.
mtcars_sub <- mtcars[1:5,c("mpg", "hp", "disp")]
pmap(mtcars_sub, sum) #WORKS!!!!
pmap(mtcars_sub, sum(na.rm = F)) #WHY NO WORK???

Use ... to pass arguments to the mapped function.

library(purrr)
mtcars_sub <- mtcars[1:5,c("mpg", "hp", "disp")]
pmap(mtcars_sub, sum)

@Nick1991

df_list <- map(filelist,read_excel(col_names = F)) #WHY NO WORK???

or use the ~ notation

df_list <- map(filelist, ~ read_excel(.x, col_names = F))
