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) ------------------------------------- David L Carlson Associate Professor of Anthropology Texas A&M University College Station, TX 77840-4352 -----Original Message----- From: r-help-boun...@r-project.org [mailto:r-help-boun...@r-project.org] On Behalf Of philippe massicotte Sent: Wednesday, September 4, 2013 1:34 PM To: r-help@R-project.org Subject: [R] Histogram 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 [[alternative HTML version deleted]] ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
