similar to: hist(.) -- S compatibility : [a,b) versus (a,b] and ....

I discovered a bug in hist(). Try the following: x<-c(-5,-4,-4,-4,-3,-3,-3,-3,-2,-2,0,0,0,0,1,1,1,3,3,5,6) # Note that sum(x)<0: sum(x) # [1] -13 hist(x) # looks ok hist(x,freq=F) # negative bars !! # and finally this gives not 1: sum(hist(x,plot=F)$rel.freqs) # [1] -0.8076923 The reason is, that "sum(x)" is used instead of "length(x)" in the following line near

Hi, would it be possible to change the hist() function in future R Versions to accept a "plot=F" parameter (like hist() in S it should return a list with "breaks" and "counts" in this case). This change should be very simple. Albrecht ------------------------------------------------------------------------------- Albrecht Gebhardt email :

Hi, if I dermine the break points using the hist() function and then try to re-use these in a new histogram, R fails. Here is an example of the problem: ##First, plot a histogram: data(islands) foo <- hist(islands,freq=T) ##Now, try plot it again, with the previously determined break points: hist(islands,breaks=foo$breaks,freq=T) ##... this lead to the warning message: Warning message:

I think there are a couple of things in ?hist that are not quite as clear as they could be. (1) freq: logical; if 'TRUE', the histogram graphic is a representation of frequencies, the 'counts' component of the result; if 'FALSE', _relative_ frequencies ("probabilities"), component 'density', are plotted. Defaults to

Dear All, I am a undergraduate using R for the first time. It seems like an excellent program and one that I look forward to using a lot over the next few years, but I have hit a very basic problem that I can't solve. I want to produce a standardised histogram, i.e. one where the area under the graph is equal to 1. I look at the manual for the histogram function and find this: freq:

Going over my old notes, I realised that hist() has changed since the earlier versions of R, in that the intervals are now left-open,right-closed rather than the opposite. This is a change in the direction of S-plus compatibility, but I wonder how sensible it really is. The main problem is with ages, where you'd naturally take age 17 as representing something between 17 and 18, but: >

I'm forwarding this to R-bugs. In R 1.2.1 the file $R_HOME/bin/maketitle.awk is installed as an executable. It should not be since it is just a set of awk commands, not a script file that can be run from the shell (This is a change from R 1.2.0 in which the file $R_HOME/bin/maketitle was a shell script). This confuses an rpm utility called "find-requires" which scans all executable

Dear all, I am encountering a problem with lattice in the current version 0.14-13 with R version 2.4.0 on a Windows XP system. For example, histogram(~voice.part, singer) is not labeling the x labels according to the factor levels of voice.part, which it should do (and has done in former versions of lattice, as far as I remember). In addition, I get the warnings Warning messages: 1:

In current versions of R, pretty(333) gives an infinite loop (due to a silent integer overflow in src/appl/pretty.c). I've looked at this problem and also at what S-plus does, (no code there to inspect, just experiments), and then I have fixed pretty.c. I think that it now behaves much more reasonably (both than before and than S / S-plus). The only problem: pretty(.) is not

There were some questions about hist() a couple of days ago which triggered this post. My question/suggestion is about the y-axis in hist. There are reasons to prefer making the y-axis density=relative frequency/bin width. One reason is that the height of the plot does not depend on the bin width; another is that if your histogram is in density then you can easily superimpose a smooth theoretical

Full_Name: Dr. Bernd Winkler Version: 1.2.2 OS: Linux Submission from: (NULL) (194.59.179.176) Hi all, having updated to version 1.2.2 last week I experienced some strange behaviour of the hist function. I want to plot a histogram of frequencies resp. counts, for example poisson random numbers, on a predefined and fixed x scale > hist(rpois(500, 2), breaks=0:10) But instead of the

Hi, I have a casting/formatting question on hist.POSIXt: The histogram plot from POSIXct works perfect (with help of Prof. Ripley -thanks!). When processing the hist(plot=FALSE) output and then plotting the results over the x-axis (bins) coming from hist(), I lose the date/time labels, getting instead integers displayed. Trying to cast the $breaks with as.POSIXct gives silly results with

Hello! Up to now I have been using hist() to display the distributions. Howevere, I noteiced strange numbers on y (vertical) axis, if I used probability = T or freq = F option. I thought it is a bug and launched the R-bug system and found some posts on that matter. Brian Ripley responded to one, that one should look at truehist() for that. Ok I can use truehist() if I want to see the ratios

Hello, I have a problem with the hist() function and showing densities. The densities sum to 50 and not to 1! I use R version 2.9.1 (2009-06-26) and I load the seqinR library. My data is the following vector: [1] 0.1400000 0.2000000 0.2200000 0.2828283 0.1600000 0.1600000 0.3600000 [8] 0.1600000 0.2200000 0.2600000 0.2000000 0.3000000 0.2200000 0.2342342 [15] 0.1800000 0.2200000 0.1600000

Currently I'm porting the spatial library from "Venables W.N., Ripley, B.D. (1995): Modern applied statistics with S-PLUS, Springer" to R. Now it seems to work with R-0.50-a4, but I guess it has to be adjusted when R 0.60 comes out. So my questions are: What changes will appear in library sources (directories, Makefile, help page format)? Can I get an unofficial pre-version
