Histogram help!!

d=read.csv("antibody.csv", header=T)
hist(as.numeric(screen(1,35)), breaks=20, main="Antibody", xlab = "Day", ylab = "Amount of tests", xlim=c(0,18), ylim=c(1,35), freq = FALSE)

My histogram is not coming out properly and it has no bars on the graph. I am hoping that someone would be able to help me. Thanks so much!

Hi, welcome!

We don't really have enough info to help you out. Could you ask this with a minimal REPRoducible EXample (reprex)? A reprex makes it much easier for others to understand your issue and figure out how to help.

If you've never heard of a reprex before, you might want to start by reading this FAQ:

an obvious issue even without accessing your data is that there is no relationship between the object d that you load with read.csv() and the subsequent call to hist()
