I'm trying to do a post-hoc test with the glht() function from the multcomp package. I receive an unexptected symbol error and I don't understand why.
Please find the example of the dataframe which should reproduce the error. It's my first question here and please forgive me if I didn't get the reprex perfect.
Many thanks in advance!
df1 <- data.frame(credit_amount = c(1169,5951,20960,78820,4870,9055,2835,6948,3059,5234), job = as.factor(c("skilled","skilled", "unskilled resident","skilled","skilled", "unskilled resident","skilled", "high qualif/self emp/mgmt", "unskilled resident", "high qualif/self emp/mgmt")) ) lm.credit <- lm(credit_amount ~ job, data = df1) library(multcomp) ph.test.1 <- glht(model = lm.credit, linfct = mcp(job = c("unskilled resident - skilled = 0"))) summary(ph.test.1)
