I am absolutely new to R and I am aware of only a few basic command lines. I was running a robust regression in R, using the following command line
library (MASS) rfdmodel1 <- rlm (TotalEmployment_2004 ~ MISSISSIPPI + LOUISIANA + TotalEmployment_2000 + PCWhitePop_2004 + UnemploymentRate_2004 + PCUrbanPop2000 + PCPeopleWithACollegeDegree_2000 + PCPopulation.of.or.over.65.years.of.age_2004) summary (rfdmodel1) But, I keep getting this error: Error in eval(expr, envir, enclos) : object 'TotalEmployment_2004' not found > summary (rfdmodel1) Error in summary(rfdmodel1) : object 'rfdmodel1' not found I have tried using a different machine and that did not work either. Any suggestions?
