A factor or numeric variable name to be charted, in quotes.

subgroup

A factor variable name that subgroups cases, in quotes.

nlabels

A logical argument. Default is FALSE. If TRUE, the subgroup levels will be changed to include the unweighted sample sizes ("subgroup (n=xx)").

                                      conlegis %in% c("A GREAT DEAL", "ONLY SOME", "HARDLY ANY"))

#Factor variable with weights
tbl_chart(gss_data1, "conlegis", "region", "wtssall")

#Factor variable without weights
tbl_chart(gss_data1, "conlegis", "region")

#Numeric variable with weights
tbl_chart(gss_data1, "coninc", "region", "wtssall")

#Numeric variable without weights
tbl_chart(gss_data1, "coninc", "region")
