Why are all of my students histograms being labeled as "Count" on the vertical axis of a histograms, except for 1 student who is is getting "Density"?
One possible cause is that uneven breaks result in a density plot in the hist() function.
set.seed(123) VEC <- rnorm(100) hist(VEC, breaks = seq(-3,3,0.5))
#uneven breaks -> density on y axis hist(VEC, breaks = c(-3,-2.5,-2,-1.5,-1,1,1.5,2,2.5,3))
#force frequency hist(VEC, breaks = c(-3,-2.5,-2,-1.5,-1,1,1.5,2,2.5,3),freq=TRUE) #> Warning in plot.histogram(r, freq = freq1, col = col, border = border, angle = #> angle, : the AREAS in the plot are wrong -- rather use 'freq = FALSE'
