Being new to R, and also to this forum, I apologise if I am posting the question in an unclear manner.
I am using lme4 to run linear mixed model. The model itself works, my problem is in plotting its output with plotLMER, since I would need to add the standard error of the mean with the error bars, but cannot find a way to do it. Thus far, I my code is (data is added below):
read.table("data.txt", header=T) -> data
library(lme4)
m1 <- lmer(log(IA_FIRST_RUN_DWELL_TIME) ~ SEMANTIC*SYNTACTIC + (1|SUBJECT) + (1|SENTENCE_ID), data=data);
library(languageR)
plotLMER.fnc(m1, fun=exp, ylab='Dwell time (ms)', pred='SEMANTIC', lwd=3, font= 2,
font.lab= 2, xlabs = 2, linecolor = 3:5,
intr=list('SYNTACTIC', c('cong','incong'), 'end'),addlines=T)
The model works and the plot shows fine, but, as mentioned, I would need to add error bars to it - and this is where I got stuck.
So far I wasnt' able to find an answer to this question anywhere, so any help would be very much appreciated. Thanks! Cata
