How do you take care of variable with missing values when plotting?

[humphrey kimani]

Hello,

I have a problem..

I have been plotting some data here..of gender( Female and Male).. you will
find in the data were missing gender.. when I am plotting eg a bar graph I
get 3 bar- I expected 2 but its graphing those with missing gender as a
variable...I don't want then to be included when am graphing.
Would any one help me how to go about it..

Regards

Humphrey & Lorine

It would help us to help you if you could produce a small reproducible
example: data and code that illustrate the issue. Not neccesarily your
actual data, if that is private or overly large. The package 'reprex'
can help you ith this, but setting up some data including it via dput
in the email along with code that you've used on this data set would
help.

Ron.

Hi Humphrey & Lorine,

I believe ggplot will by default plot all levels of a factor including NAs.

To exclude the cases/lines with NAs for gender, do something like this
and then plot the new object.
This code assumes one data frame (df) with a column named 'gender'
where you coded FEMALE, MALE and have the NAs.

df2 <- df[!is.na(df$gender), ]

Hope this helps
Tom
