'Error when creating waffle chart - object cannot be coerced
Attempting to make a simple waffle
chart with the below vector pie
:
rideable_type number_of_trips
<ord> <dbl>
1 Classic 58
2 Electric 36
3 Docked 6
The function I am using is:
waffle(pie, rows=6)
This function returns the following error:
Error in FUN(X[[i]], ...) :
'list' object cannot be coerced to type 'double'
I'm sure that error is because rideable_type
is characters
, because when I run:
waffle(pie$number_of_trips, rows=6)
It runs just fine, but the legend names are A
, B
, C
. I just want the the legend to correspond to the rideable_type
. I'm sure I could do that manually...but it seems unnecessary. Thank you.
Solution 1:[1]
I figured out I can use setNames
to solve the problem:
pie <- setNames(pie$number_of_trips, c('Classic','Electric','Docked'))
waffle(pie, rows=5, legend_pos='bottom')
Produces what I need:
I realized that waffle
thought my vector was unnamed. I believed the function would automatically use the first column. Still not sure waffle
doesn't, but this solved my question.
