Hi, I want to use hist with non-equi-spaced breaks, picked such that the fraction of the data points falling in the cells (defined by 'breaks') is roughly equal accross all cells. Is there such a function that will automatically try to determine the breaks to fullfill this requirement? Something like.. hist( x, br = magic_function_to_pick_breaks()) For example, if x looked like

I want to make a log-log plot with a regression line, but I can't figure out what I'm doing wrong. What I'm trying is: plot(mass,area, log="xy", pch=as.numeric(food)) abline(lm(mass~area)) or plot(mass,area, log="xy", pch=as.numeric(food)) islands$logmass <- log(mass) islands$logarea <- log(area) attach(islands) abline(lm(logmass~logarea)) But that does

Full_Name: Fran Rizzardi Version: 0.90.0 OS: Solaris, NT 4.0 Submission from: (NULL) (128.32.135.223) If you use the horiz= option with hist() you get the message: Warning: parameter "horiz" couldn't be set in high-level plot() function. and the plot comes out vertical. The documentation says this option comes from barplot() and it does work correctly in barplot(). This

Hi all, I wish to draw 2 hist (or barplot) on the same graph. I can do it simply by using par(new=TRUE) , but it overlap with the first drawn, how to tell R to put in front of the graph the min value of the two graph in order for it to be seen and don't hide each other. I've been looking at help for barplot or hist but didn't find anything... (or my english is too poor to

I would like to plot two data sets (frequency (y-axis) of mean values for 0-1(x=axis)) on a single histogram for comparison. The hist() only allow the overlay of two histograms, and although barplot() allows beside=TRUE, it does not show frequency values (like hist) but rather all of the values. Is there any way that I can use the hist() to plot two data sets similar to the barplot(). Any help or

I'm working on a quick tutorial for my students, and was planning on using Mann-Whitney U as one of the tests. I have the following (fake) data grade <- c("MVG", "VG", "VG", "G", "MVG", "G", "VG", "G", "VG") sex <- c( "male", "male", "female", "male",

Hello dear useRs and wizaRds, I encountered the following problem using the hist() method for the 'times' classes from package 'chron'. You should be able to recreate it using the code: library(chron) # pasted from chron help file (?chron) dts <- dates(c("02/27/92", "02/27/92", "01/14/92", "02/28/92", "02/01/92")) class(dts)

Hi all I wish to draw an histogram... with dates but the following append, i don't know where is the problem, help(hist.Date) works and i don't see any usefull information on what i'm doing wrong... > hist.Date(dt_cycles) Error: couldn't find function "hist.Date" > hist.date(dt_cycles) Error: couldn't find function "hist.date" > cycles [1] 7 1

I teach biology, and would like to show the students how to use R for some statistical assignments. One of those is to make a kite diagram (for example as seen in http://www.medinavalleycentre.org.uk/images/Bembri1.jpg). Is there any way to create one using R? I did a help.search("kite") and looked on the r-project HP with no luck. Previously when the course was taugh the students have

Hi, i created a set of graphs and want to find out how to swap the bar colours (from white to black) and set it to be default for all graph that i will produce (f.e. for different number of columns). some sugggestions? thanks in advance. here is an example: ############################## a <-read.table("http://www.scandinavia.sk/data/R/kotlina1.csv", sep=";", header=T)

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 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

I want to make a histogram from the lengths vector which is part of the output of rle. But I don't know how to access that vector so that I use it as an argument of hist(). What argument must I use so that I use the lengths vector as an input to hist()? Example output is: Run Length Encoding lengths: int [1:4] 1 2 3 3 values : num [1:4] -1 1 -1 1 A printout of the function rle() may

Hi All, When carrying out hist(samples,breaks=50,probability=TRUE), the column values are considerably greater than 1, which seams very unreasonable. The plot is attached. I think the column value of the hist plot should correspond to x$counts/sum(x$counts) (x=hist(samples,breaks=50,probability=TRUE)). The size of data is a little bit larger, causing failure of uploading. If you need the

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

A quick question, please. x = c(0.0001, 0.0059, 0.0855, 0.9082) y = c(0.54, 0.813, 0.379, 0.35) where A = 1st set, B = 2nd set, C = 3rd set, D = 4th set respectivley. How do you make hist plot side by side for x & y? i.e. 0.0001 and then to the right 0.54, 0.0059 and then to the right 0.813, etc. thx much [[alternative HTML version deleted]]

The command hist(c(2,2,2,4,5,6)) returns a histogram that looks incorrect -- 3 in the bin labeled 2 on the left, but 1 each in the bins labeled 3,4,5 on the left. Thanks!

I would like to ask if there is some simple way for building a hist from the following data. mm <-c(2,3,0,4,5,0,2,9,0) mmm <- matrix(mm,ncol=3, nrow=3) x <- c(0,1.45,2.9) in mmm there are frequencies (each column is separate histogram and each row corresponds to value of x). So that for the first histogram we have 2 times interval [0,1.45] and 3 times [1.45,2.90]. Thanks a lot!

Hi, If you want to export a single bar chart, this works: > png( "ET" ); > barchart( data[,"ET"] ) > dev.off() quartz_off_screen 2 But if you want to export a few of them, this does not: > factorCols <- c("MR","ET"); > sapply( factorCols, function(x) { + png( x ); + barchart( data[, x] ); + dev.off(); + } );
