Unexpected token error

[SarahPotts]

Hi, my supervisor sent me some files in R and when I try and open them, I get the message saying unexpected error next to the r at the beginning of these scripts:

library(kableExtra)
out_varsRT<-FlankCueDF%>%
dplyr::group_by(Subject)%>%
dplyr::summarise(meanMRT=as.numeric(mean(rt))/1000) %>% 
  dplyr::mutate(Subjecttype = ifelse(meanMRT>1.5, "badSubject", "goodSubject"))

anyone know why?  Thank you

See the FAQ: How to do a minimal reproducible example reprex for beginners. The data hasn't to be all the data or even real data—just enough to illustrate the problem. The object FlankCueDF or something with its structure is needed to help.
