RERI incorrect due to variable names

[Daniel-Rud]

Hi,

Just wanted to share a problem when I use Y ~ E + G + E:G. When you use the line
e1 <- grep(exposure_names[1], names(coef(model)), value = TRUE, ignore.case = TRUE)
e2 <- grep(exposure_names[2], names(coef(model)), value = TRUE, ignore.case = TRUE)
e1_e2 <- intersect(e1,e2),

the E variable is picked up as the "(Intercept)" variable. Thought id share, looks like more prone with short single letter variable names.
