similar to: hist and truehist

Hi, I'm wondering how can I change the position of xlab in truehist. For example, the following code creats a histogram with 4 bins for my discrete data. I want each bin to be labelled as 0, 1, 2, or 3 in the middle, so that it's clear each bin corresponds to each of the discrete case. I was thinking of first delete xlab and then add marks myself, but it doesn't look like it's

Hi, I have a simple problem that I would appreciate getting some tips. I am using the "truehist" function within an "apply" call to plot multiple histograms. I can't figure out how to get truehist to use the column names of the matrix as the labels for the x-axis of the histograms. Here is a simple example: X <- matrix(runif(4000),ncol=4) colnames(X)

rdevel from yesterday, also in 1.9.1 (Debian, -3). The man page of 'hist' (from the graphics package, obtained by "?hist") suggests 'truehist' under "see also", but 'truehist' isn't loaded by default (a sensible "of course"), so that "?truehist" fails. One can do help.search(), of course, which points what to do, but leads to my

Hi, I wanted to plot the histogram of a vector and then, plot the density function of subsets of the vector on the histogram. So I use truehist in MASS package and lines(density) as follows: length(b) = 1000 truehist(b) lines(density(b[1:100])) however the density plot of the first 100 points exceeds the max of y axis (see attached). how is it possible to make a graphics so that the density plot

Hello, After a long time, I needed the truehist function, but my system couldn't found it. I tried to install the package MAAS, but I couldn't found it! Something happened?

Dear Rologists, In order to combine plots I need to get access to the some "par"s specific to my plot prior to replot it with modified parameters. I have not found any option like "plot=F" associated with truehist and would like to know whether someone can point out how to overcome this problem. Thanks, Joh

Dear People, I am sure I am missing something obvious as usual, but in the following graph I can't plot ylab. Ignoring unimportant details, I am plotting one instance of truehist() and one instance of curve() on the same graph. Truehist() won't let me pass the ylab argument. It gives me the error Error in plot.default(xlim, c(0, ymax), type = "n", xlab = xlab, ylab =

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

Hi there, # Consider the following example: A = 19 B = 20 A< B A==B hist(c(1:15,B,50),breaks=c(0,15,A,50),plot=F)$count hist(c(1:15,A,50),breaks=c(0,15,B,50),plot=F)$count # I was expecting the same results with the following values of A and B: A = 19.6019203953960 B = 19.6019204365543 A< B A==B hist(c(1:15,B,50),breaks=c(0,15,A,50),plot=F)$count# wrong

>selectiris<-sample(1:5, 150, replace=T) > hist(selectiris, plot=TRUE) #freq=TRUE, breaks=5, etc all do the same thing >truehist(selectiris) Is the behavior of "hist" in this sample of code correct. On my system (Windows 2K, SP2) the first and second bars are pushed together, while the 3rd, 4th, and 5th bars are correctly positioned. The function "truehist"

Dear People, I have a data set of data x from a probability distribution, and I have a function, mydensity, of the pdf of that distribution. I'm asking for help in superimposing the histogram of x and the plot of mydensity. In the function below, I call truehist and curve, but these are plotted in different figures. I'd like them to be plotted on the same figure, and to use common

Hello fellow R users, I wanted to view the density on the standard deviation scale of a gamma(0.001, 0.001) prior for the precision. I did this as seen in the code below and found that for some reason rgamma is giving many values equal to zero, which is strange since a gamma distribution is continuous. What is going on here? Thanks for any help in advance. Greg > x1 <- rgamma(10000,

Hi, I am trying to label the x-axis of some histograms with the units of measurement. However, when I use, for example: > truehist(Ca, prob=FALSE, col="gray", xlab=expression(paste("Calcium (", mu, eq^-1, ")"))) I get the following message: Error in eval(expr, envir, enclos) : Object "mu" not found Could someone let me know what I'm doing wrong?

My R installation (Mac OS9.2.2) is working, but when I try to run the examples from Venables & Ripley (p. 6): R : Copyright 2001, The R Development Core Team Version 1.4.0 (2001-12-19) ... > library(MASS) > x<-rnorm(1000) > y<-rnorm(1000) > truehist(c(x,y+3),nbins=25) % Plots nicely > dd<-con2tr(kde2d(x,y)) % Doesn't complain > contourplot(z ~ x + y,

I have problems getting a histogram with relative frequencies on the y-axis. Here is an example data set: > a <- c(4.626, 4.627, 4.627, 4.628, 4.629, 4.629, 4.630, 4.631, 4.632, 4.632) > d = hist(a,freq=F) > d$density [1] 299.9999 100.0000 200.0000 100.0000 100.0000 200.0000 The obtained densities are given by counts/(total n * bin width), with bin width being

Dear all, hist ( ) plots a horizontal line at y=0 when the respective bin is empty. I can deal with this by modifying the hist object before plotting it (x$density[x$density == 0] <- NA), but I'm sure I've seen a more elegant way. Perhaps this was in truehist (MASS). I have looked but can't find it. Does anyone know? Best wishes Paul -- View this message in context:
