Hi,
I am running through a series of regression in a loop as follows:
results <- vector("list", length(mydata$varnames))
for (i in 1:length(mydata$varnames)) {
results[[i]] <- summary(lm(log(eval(parse(text=varnames[i]))) ~ age + sex +
CMV.status, data=mydata))
}
Now, when I look at the results[i]] objects, I won't be able to see the
original variable names. Obviously, I will only see the following:
Call:
lm(formula = log(eval(parse(text = varnames[i]))) ~ age + sex + CMV.status,
data = mydata)
Is there a way to display the original variable names on the LHS? In addition,
is there a better paradigm for doing these type of series of regressions in an
automatic fashion?
Thank you very much,
Ravi
