Dear,
I am having a lucky day. I am programming in RStudio and when I type
"black" (quotation signs included, the word turn into a word with black
ground. Couldn't get rid of the background----copying to Word, Excel,
text editor and paste back to Rstudio, the word is still in black
background? Help!
dv.group<-c("black","othrrace"); cat.ref<-"white"
