[R] Histogram

[David Carlson]

We can just ask hist():

? hist

. . . 

breaks 	

one of:

    a vector giving the breakpoints between histogram cells,

    a function to compute the vector of breakpoints,

    a single number giving the number of cells for the
histogram,
================================================================
=
    a character string naming an algorithm to compute the number
of cells (see 'Details'),

    a function to compute the number of cells.

In the last three cases the number is a suggestion only.
========================================================

In this case hist has decided to ignore you. You can overrule by
specifying the breaks:

hist(1:10, 0:10+.5)

Hi everyone.
I'm currently translating some Matlab code into R. However, I
realized that the hsit function produce different results in
both languages.
in Matlab, hist(1:10, 10) will produce 10 bins with a count of 1
in each, but in R it will produce 9 classes with count of
2,1,1,1,1,1,1,1,1.
I'm a bit embarrassed to ask such question, but why R is not
producing 10 classes as requested?
Thanks in advance,Phil
