similar to: Thin bars in R hist !!??

Hello, Could someone explain to me why I get so different histograms, in terms of bar spacing, depending on the number of counts entered ? (see example below) > test <- c(0,1,1,1,1,0,0,0,0,0,2,3,2,2,2,3,3,4,5,6,7,5,4,3,4,2,2) > hist(test) I obtain this kind of histogram (what I actually want), i.e. large bars with no space between them x xx xxx xxxx xxxxx xxxxxx

I am sure this is trivial, but I cannot solve it. I make a histogram. There are 5 categories "1",...,"5" and 80 values and the histogram does not evenly space the bars. Bars "1" and "2" have no space between them and the rest are evenly spaced. How can I get all bars evenly spaced? The code: > Q5 [1] "4" "4" "4"

Hi all, I'm plotting a histogram of dates and would like to shade the bars, e.g. hist(.leap.seconds,"years",col='gray',freq=T) -but the axis color also changes, how do I prevent that? thx in advance Janus [[alternative HTML version deleted]]

Hi: The y axis on the hist function seems to set its limits oddly. sometimes, it covers the full range of the data and sometimes it stops one major tick short. I have had this behavior with a variety of data sets, and it can easily be reproduced by just running the following several times: hist(rnorm(100000)) I have tried explicitly setting ylim to the range of values produced by rnorm

Hi, I have the following code: hist(gps$heartpercent, breaks=5) rect(90, par("usr")[3], 100, par("usr")[4], col = "red") How do I get the rectangle to appear behind the histogram. Barring that, how can I make certain bars of the histogram to be a certain color? Thanks, Jason

Full_Name: Mark Wall Version: 1.6.0 OS: linux Submission from: (NULL) (63.251.119.254) I want to plot a histogram of a *subset* of some data: >t = c(0:9) >hist(t,right=FALSE,breaks=10,xlim=c(0,5),xaxs="i") This means I should plot a histogram from 0 to 5 with breaks at 1,2,3,4. This should produce exactly 5 bars of frequency=1. Instead I get 5 and 1/4 bars. I do not want the

Hi, It seems that hist() has a buggy behavior when breaking over "days". The bug can be reproduced in a few steps: > d=data.frame(date=c("2009-01-01", "2009-01-02", "2009-01-02")) > d$date=as.Date(d$date) > d$date [1] "2009-01-01" "2009-01-02" "2009-01-02" > h=hist(d$date, "days") > h$count [1] 3

Hey everybody, I try to make a graph with two different plots. First I make a boxplot of my data. It is a collection off correlation values of different pictures. For example: 0.23445 pica 0.34456 pica 0.45663 pica 0.98822 picb 0.12223 picc 0.34443 picc etc. Ok, I make this boxplot and I get for every picture the boxes. After this I want to know, how many correlations per picture exist. So I

I've got a few issues with the x-axes in the histogram and density plots. First, often the default x-axis doesn't even extend to the length of my data. R often draws histogram bars (or density lines) farther than the drawn x-axis extends. For example, I might have a histogram bar at -15,000. But I wouldn't know that, because the most negative number on the x-axis is -10,000. The

Hi, This is a very basic question, but I would like to undestand hist(). I thought that the hist( , freq=FALSE) should provide the relative frequencies (probabilities), and so they should sum 1, however: set.seed(2) ah <- hist(rnorm(100), freq=F) sum(ah$intensities) [1] 2 set.seed(2) bh <- hist(rlnorm(100), freq=F) sum(bh$intensities) [1] 0.4999996 I'm getting similar figures with

To whom it may concern, I have a problem concerning the design of a histogram. How do I change the border widths of the bars of a histogram. The initial command is: hist (punkte,breaks=30, xlab="Punkte", ylab="H?ufigkeit", main="Histogramm", col= heat.colors(30), border= "red") I suspect that it has to do with the "lwd" command but can't

Dear listers, A quick question about breaks in hist(). The histogram is highly screwed to the right, say, the range of the vector is [0, 2], but 95% of the value is squeezed in the interval (0.01, 0.2). My question is : how to set the breaks then make the histogram look even? Thanks in advance, Leaf

Think I'm missing something to understand what is going on with hist(...) http://n2.nabble.com/What-is-going-on-with-Histogram-Plots-td3022645.html For my example I count 7 unique years, however, on the histogram there only 6. It looks like the bin to the left of the tic mark on the x-axis represents the number of entries for that year, i.e. Frequency. I guess it looks like the bin for

. I am looking for a histogram or box plot with the adding normal distribution curve I think that must be possible, but I am not able to find out how to do. Regards Knut

Dear List, I have the following function where I plot on one page a histogram and a boxplot. I use option labels = TRUE in hist to show labels. However the label on the highest bar in the histogram is not showing entirely. How can I correct this? Thanks for any suggestions? histtst <- function(n = 100,...){ set.seed(15) # makes rnorm reproducible par(mfrow = c(2,1)) x <-

Hi all, I'm trying to superimpose a rchisq density line over a histogram with something like: hist(alnlength) lines(density(rchisq(length(alnlength), 4)),col="red") But the rchisq line won't appear anywhere, Anyone knows what I am missing here? Thanks in advance, Albert.

Hi there, I really couldn't find out how to plot histogram with point/line instead of rectangle for each bin? Any help please? Thanks! Best, -Cao

Dear everybody! I have load a list A of numbers and want a histogram to be drawn. on hist(Y) the Machine returns: Error in hist.default(A) : `x' must be numeric I found out, that the list is of type data.frame. Y<-as.numeric(Y) returns Error in as.double.default(A) : (list) object cannot be coerced to double What schould I do? Than you in advance!

Hi, I've been passing the hist() function to tapply() to quickly generate histograms based on the list of factors supplied to tapply(). However, I have not figured out how to generate titles for each of the histograms, which paste in the unique values of the list factors as part of the histogram title. I'm hoping that someone can tell me how to do this. Thanks for your time and
