Hello,

I have code that works perfectly when run as in-line code, but that fails when
the code is put into a function with the following message:
Error in contest1D.lmerModLmerTest(model, ll, rhs = rhs, ddf = ddf, confint =
confint, :
length(L) == length(model@beta) is not TRUE
Why does moving the code to a function lead to an error? What can I do to avoid
the error?
Thank you,
John
In-line code:
fit2aCort <- lmer(SBP~age+jFStage+AHIgt5+jFStage*AHIgt5+(1|patid),data=alldata)
c1 <-c(1, 5.99, 1, 0, 0, 1, 0 )
c2 <-c(1, 5.99, 0, 1, 0, 0, 1 )
model <- fit2aCort
s1a <- contest(model,L=c1,joint=FALSE)
s1as1E <- s1a$Estimate
s2a <- contest(model,L=c2,joint=FALSE)
s2E <- s2a$Estimate
Time <- c(1,2)
SBP <- c(s1E,s2E)
plot(Time,SBP)
title("Predicted Sys SBP, age 5.99 yr (SS 524 obs with BP 190mmHg removed)")
plotCI(Time,SBP,uiw=1.96*c(s1a$"Std. Error",s2a$"Std. Error"))
Code put into a function that fails:
plotit <- function(c1,c2,model)
{
s1a <- contest(model,L=c1,joint=FALSE)
s1as1E <- s1a$Estimate
s2a <- contest(model,L=c2,joint=FALSE)
s2E <- s2a$Estimate
Is s1as1E a typo? The way you define and use s2E suggests that it should be
s1E <- s1a$Estimate
Hope this helps,
