I am trying to build a histogram with the Github diabetes dataset by using the variable "heights." But I receive the error which said data must be a data frame, or other object coercible by fortify(), not an integer vector. What should I do?

[test102950]

diabetes <- read.csv("https://raw.githubusercontent.com/malcolmbarrett/au-stats412-612-01-reading_data/master/diabetes.csv")
just_height <- diabetes[, "height"]
ggplot(just_height, aes(x = height)) + 
geom_histogram()

Because you select only one column the one-column data.frame is converted to integer.
Annoying I think. Avoid this by specifying

just_height <- diabetes[, "height",drop=FALSE]

There is no need to create a vector with just the "height" variable; aes(x = height) is enough.

library(ggplot2)

diabetes <- read.csv("https://raw.githubusercontent.com/malcolmbarrett/au-stats412-612-01-reading_data/master/diabetes.csv")
ggplot(diabetes, aes(x = height)) + 
  geom_histogram()
#> `stat_bin()` using `bins = 30`. Pick better value with `binwidth`.
#> Warning: Removed 5 rows containing non-finite values (`stat_bin()`).
