I have recently started learning R. I converted a Stata datafile into an R image file, but I am unable to do anything with the data. For example, I am unable to calculate the mean of any variable or create a scatterplot of some of the data. I always get a message saying, "Error in plot(rgnpc, incmean) : object "rgnpc" not found" when I attempt to make a simple plot of the two noted variables. I get the following when I attempt to get the mean of a particular variable: "Error in mean(incmean) : object "incmean" not found."
What should I do?
