When preparing a series of histograms I found that hist was combining
the two lowest categories or bins, 1 and 2. Specifying breaks, as
illustrated below, resulted in the correct histogram:
values <- sample(10,500,replace=TRUE)
hist(values)
hist(values,breaks = 0:10)
Apparently, the number of values strictly less than 1 is shown in the
first bin (and since none is less than 1, the value is 0), while the
other bins appear to show the number of values less than or equal to the
bin's upper bound. Is there a setting that will show the number of
values less than or equal to the first bin's upper bound?
And, while on the subject of hist, what commands govern the axis label
line that shows the values of x? Is there an option that will cause it
to show all values from lowest to highest rather than by jumps of 2 or
5?
With thanks for any suggestions
