If your groups have different sizes, it might be hard to compare the shapes of the distributions of each one. and in the histogram although I put alpha=0.3, I can't see both histograms well. First well take a look at the factor levels, then well assign new factor level names in the same order, and save this new data set as birthwt_mod: Now when we plot our modified data frame, our desired labels appear (Figure 6.5). I could do this: But what this is giving me are two different histograms side by side. I leave this here in case it might be useful. What are the advantages of running a power tool on 240 V vs 120 V?
