tidyverse

Hi, can somebody help me with this error?
library(ggplot2)
setwd('d:/Aidaf/Enrichr/BP')
BP=read.delim('BP.TXT')
BP1=ggplot(BP, aes(x=RF , y=Term)) +geom_point(aes(colours=P-value , size=Genes)) +scale_colour_gradientn(colours=rainbow(5)) +labs(x='Rich Factor' , y=NULL , colour='P-value' , size='Genes')+
theme(axis.title=element_text(face='bold') , axis.text = element_text(face='bold'))
pdf("BP.pdf") ; BP1;dev.off()

Error in geom_point():

First, change the aesthetic from colours to colour. Does that help

tnx, I changed that, it doesn't work..

that was good advice, because only color and colour are aesthetics and colors/colours (plural) are not.
aside from that you have a variable called P-value this will confuse R into thinking you have a variable called P and one called value and you want to subtract them ...
either

  1. rename your variables in an earlier step , something like p_value would be good
  2. if you need to refer to it with its current name use a pair of backticks to quote it so R knows its one symbol, like this
geom_point(aes(colour=`P-value`

Thank you very much.
I replaced it with 'P.value' and it works...
I greatly appreciate your advice.
