I have the following table that I want to plot in R
A B C NA
0 500 200 200 0
This table is generated from a variable. I had previously removed the NAs using data<-data[!(data$pid3==""),]
If I use the plot()
function with this variable, the NA and "" shows up in the plot. How do I get rid of this in the plot?
Thank you!
There is a difference between ""
and NA
in R:
> is.na("")
[1] FALSE
> is.na(NA)
[1] TRUE
If you want to remove NAs, you should use something like this:
data <- data[!is.na(data$pid3),]
(It may be a good idea to remove empty strings as well, so you can run the command above in addition to your previous filtering step.)
I figured it out. I was able to achieve this using the ggplot2
package.
I generate the table using
table <- data %>% group_by(pid3) %>% summarise(n = n())
Then I plot using ggplot2
ggplot(table, aes(x = pid3, y = n)) +
geom_bar(stat="identity", position=position_dodge()) + theme_classic()
