[R] Help with declaring factors in a function

[Evan Kransdorf]

Hello,

I am passing a df to a function and then want to declare factors (based on
a vector of column names in the df) for a logistic regression. I am having
trouble - R doesn't seem to recognize the factors as declared in the
function? Below is my code.  Does anyone have any ideas?

MyFunction <- function(x,y,z) {
#x is a data frame
#y is a formula for the regression
#z vector of factors to be declared
    name<-NULL
    temp<-NULL
    for (i in 1 : length(z)) {
        name<-paste0(substitute(x),"$",z[i])
        print(name)
        temp<-eval(parse(text = name))
        temp<-factor(temp)
        print(levels(temp))
    } #for
    model<-glm(y, x, family=binomial(link = "logit"))
    return(model)
} #func

Thanks very much!!!
