[R] Resetting Baseline Level of Predictor in svyglm Function

Hello R Users:

I am using the survey package in R for modeling with complex survey data. I am
trying to reset the baseline level of certain predictor variables being used in
a logistic regression without success. The following is a reproducible example:

library(RCurl)
library(survey)

data <-
getURL("https://raw.githubusercontent.com/cbenjamin1821/careertech-ed/master/elsq1adj.csv")
elsq1ch <- read.csv(text = data)

#Specifying the svyrepdesign object which applies the BRR weights
elsq1ch_brr<-svrepdesign(variables = elsq1ch[,1:16], repweights =
elsq1ch[,18:217], weights = elsq1ch[,17], combined.weights = TRUE, type =
"BRR")
elsq1ch_brr

#Log. Reg. model
allCC <-
svyglm(formula=F3ATTAINB~F1PARED+BYINCOME+F1RACE+F1SEX+F1RGPP2+F1HIMATH+F1RTRCC,family="binomial",design=elsq1ch_brr,subset=BYSCTRL==1&G10COHRT==1,na.action=na.omit)
summary(allCC)

##Attempting to reset baseline level for predictor variable
#Both attempts did not work
elsq1ch$F1HIMATH <- C(elsq1ch$F1HIMATH,contr.treatment, base=1)
elsq1ch$F1HIMATH <- relevel(elsq1ch$F1HIMATH,"PreAlg or Less")

#Log. Reg. model with no changes in baseline levels for the predictors
allCC <-
svyglm(formula=F3ATTAINB~F1PARED+BYINCOME+F1RACE+F1SEX+F1RGPP2+F1HIMATH+F1RTRCC,family="binomial",design=elsq1ch_brr,subset=BYSCTRL==1&G10COHRT==1,na.action=na.omit)
summary(allCC)


Any guidance is greatly appreciated.?

Sincerely,

Courtney?

hi, i think you want

elsq1ch_brr <- update( elsq1ch_brr , F1HIMATH = relevel(F1HIMATH,"PreAlg
or
Less") )
