Hello, I created a simple histogram with: myHist<-hist(myData) the object myHist now has two arrays (among the others): myHist$mids myHist$counts Since myHist$counts contains some "0", and I want to calculate the linear fit among myHist$mids and log(myHist$counts), I want remove the elements of both arrays where these "0&quo...

Hi, Currently I have a density plot generated with this snippet. Is there a way I can add a line curve on top of it? I mean in one figure __BEGIN__ myhist <- hist(x col="blue", main = "Density Plot", xlab = "Exp Level", ) __END__ - Gundala Viswanath Jakarta - Indonesia

Hi all, I defined the following ############################# myhist=function(x){ hist(x,xlab="",main="") h=hist(x) xfit=seq(min(x),max(x),length=100) yfit=dnorm(xfit,mean(x),sd=sd(x)) yfit=yfit*diff(h$mids[1:2])*length(x) lines(xfit, yfit, col="blue", lwd=2) } ############################# individually, it worked fine however,...

Hi All, I want to use "hist" to get the relative frequency plot. But the range of ylab is greater than 1,which I think it should be less than 1 since it stands for the probability. Here is my code: x<-c(1,1,1,0,0,1,1,5,1,1,0,1,1,0,1,0,1,1,0,0,1,1,1,1,1,1,1,1,1,4,1,0,2,1,1,1 ,1,1,0,0,1,0,1,1,1,1,1,1,1,1,1)

dear all, i've looked at the r-intro (chapter 10, writing your own functions) and searched the r-help archives but am still stuck at the following. i have a simple function, something like: myhist<-function(yvar) { y<-subset(myframe,yvar>1 & yvar<=150000,select=yvar) attach(y) hist(yvar) } calling it as follows: myhist(x1) gives the following error: Error in attach(y) : attempt to set an attribute on NULL what am i doing wrong here? thanks in advance, edwin

...et some data (i.e length of river) you may want to look at its distribution. Then you probably want to find which law follows this distribution, and to test the goodness of the fit. For doing this simple analysis I am writing some code schematically represented below: 1)calculate the histogram: myhist<-hist(myData, breaks=....) Question: how to calculate the standard deviation of each class of the hist? I have not seen it in the output of hist 2)Looking at the graph it seems to follow a linear model: I plot the points: points(myhist$mids,myhist$counts) Question: How to plot also the weights (...

Hi all, Is there a way to rotate a plot, e.g. a histogram, by a certain angle (90/180/270 degress)? I spent hours trying to figure out how this is done, but without success. Also, I'm looking for an equivalent to the S-Plus "subplot" command to insert a kind of "thumbnail" graphic into a bigger one. How is this best done in R? Thanks for your help Pascal

Hi! I'm having a trouble changing font size of histogram label. I have tried help(hist), but I couldn't find anything explain how to fix label's font size. Could you help me please? Thank you. _________________________________________________________________ Going green? See the top 12 foods to eat organic. 1N1653A [[alternative HTML version deleted]]

Hi, I've had some trouble figuring out how to produce a histogram in R directly given a frequency table or relative frequency table. I've looked through the documentation and mailing list, and have only found information on producing histograms given the original data set. Any help would be appreciated! An example of what I'd like to do would be to take the following frequency table:

Dear userRs, Is there a way to explicitly set an argument to a function call as missing? E.g., histogram(foo, bar, endpoints=ifelse(!missing(limits),limits,NA/NULL/whatever))) In this call I want to set a value to the endpoints argument only if the `limits' variable has been set, and leave the defaults otherwise. The only way I could do it is thus: if

Is there any way to search the console during an interactive session? I've looked and looked, and can not find one. In some add-on package, maybe? Sorry to be so basic, but help would be greatly appreciated. andrewH -- View this message in context: http://r.789695.n4.nabble.com/Searching-the-console-tp3797884p3797884.html Sent from the R help mailing list archive at Nabble.com.

Hello, I have created two histograms with: hist2d(gps2, nbins=200, col = c("white",heat.colors(16))) Both of them have the same range and the same number of bins. Now I would like to compare them bin by bin and plot the results. Could someone please tell me how to do that. I searched the man pages and the web, but couldn't find anything. Thank you very much.

i want to plot the histogram and the curve in the same graph.if i have a set of data ,i plot the histogram and also want to see what distribution it was.So i want to plot the curve to know what distribution it like. -- View this message in context: http://www.nabble.com/how-to-plot-the-histogram-and-the-curve-in--the-same-graph-tp20082506p20082506.html Sent from the R help mailing list archive at
