Using ggplot function in R error : could not find function ggplot

Question

I have installed ggplot and ggplot2 and their dependencies, but I cannot use the function ggplot; whenever I try to use it I get

Error in ggplot ... could not find function "ggplot"

I don't know where you found a copy of `ggplot`, since it's no longer available on CRAN. `ggplot2` has completely replaced it. — Andrie, Aug 10 '11 at 22:17
I would reopen. I think gsk's answer is probably the right one and its definitely a FAQ even if it's not in the FAQ. — IRTFM, Aug 10 '11 at 23:30
@DWin : it is the right answer, so no more answers needed. These kind of questions best disappear into oblivion. — Joris Meys, Aug 11 '11 at 12:54
@Joris Meys: I guess you changed your mind on that point? (Since you posted a basically an identical question later.) — IRTFM, Aug 11 '11 at 15:13
@DWin : yeah... Actually, I first thought of editing this one to make it a whole lot more general (basically cutting out the ggplot and replacing it with dots), but then again, gsk3 would have to rewrite his answer. So that's why I made that almost identical question. — Joris Meys, Aug 11 '11 at 15:16

Try:

library(ggplot2)

Even after installing a package, you have to load a package each time you load R.

This question is answered comprehensively in the r-faq:

Agree that's the most common newbie mistake that results in that error message. – IRTFM Aug 10 '11 at 23:23
after adding `library(ggplot2)` as above, I can use `ggplot` now, thx – C.K. Jun 24 '18 at 06:17
