Hi all: following the previous discussion, it looks like plot(x) with y=NULL still does not work correctly. If one tries for example plot(1:5) it works, but already for plot(runif(100)) it does not. I posted the proposed correction for plot.POSIXct and plot.POSIXlt before. Please voice your opinions whether the following fix for plot.default could be reasonable? I include the full function and

Hi all, As long as I've used R, add=TRUE hasn't worked in contexts like this: f <- function(x) x^2 X <- seq(0, 1, by=1/4) plot(f, col="blue") plot(X, f(X), col="red", type="l", add=TRUE) I attached a fix for version 2.6.2.

Hi! How to find out which plot function is used when i call plot(hist.default(1:10,plot=F)) and all works fine ? The reason why I would like to know it is that after loading some self written R functions > plot(hist.default(1:10,plot=F)) Error in xy.coords(x, y, xlabel, ylabel, log) : x and y lengths differ > traceback() 5: stop("x and y lengths differ") 4: xy.coords(x, y,

I have a need to build a time series and there are a couple of aspects about the time series object that are confusing me. First it seems that ts.union is not doing what I would expect. For example: x0 <- rep(0,10) x1 <- rep(1,10) xt0 <- ts(x0, frequency=10) xt1 <- ts(x1, frequency=10) st2 <- ts.union(xt0, xt1) > xt2 Time Series: Start = c(1, 1) End = c(1, 10) Frequency = 10

Hi, I am new to R. I am trying to figure out how to graph expression data from the TCGA database. If I understand correctly the expression data I have downloaded is from a microarray using the AgilentG4502A. I've had trouble reading into R in the level I, level II, and the gene expression analysis data using >dat<-read.table("C:\\file.txt", header=T, row.names=1) for

termplot() does not carry subsetting over to carriers that are in the environment but not in the data frame. This generates a "subscript out of bounds" error. > data(ToothGrowth) > logdose <- log(ToothGrowth$dose) > tooth.lm <- lm(len ~ logdose, data=ToothGrowth) > termplot(tooth.lm) ## Works fine > toothVC2.lm <- lm(len ~ poly(dose,2),

I am currently trying to use R to construct a regression model to explain output based on temperature.

Good day all, I'm trying to plot a continuous line plot, which is followed by two forecast points eg. one forecast point is 12 months out, and another 24 months out from the last date of the line plot. In my attempts so far, the second plot (the forecast points) is scaled against a new axis scale, thus the two plots are not directly comparable (I need the forecast points to be scaled

HI, sorry but i don't understand how to make a function with as.function() formula<-"2+3*x" formu<-as.symbol(formula) > formu 2+3*x formul<-as.function(alist(x=,formu)) curve(formul,1,5,col="blue") Error in xy.coords(x, y, xlabel, ylabel, log) : x and y lengths differ > typeof(formul) [1] "closure" and not plot the curve function, Why?

Hi i want do a line graph. My y axis contains numeric values. My x axis contains non numeric statements. This is what i want the graph to look like. When i try to plot this graph on R it comes up with the following error message: "Error in plot.window(...) : need finite 'xlim' values In addition: Warning messages: 1: In xy.coords(x, y, xlabel, ylabel, log) : NAs introduced by

Hello, I am hoping for some advice regarding warning/error messages I received when running a Cox regression # message 1 - obtained while creating a plot of residuals > plot (NV.zph, main = "groupNUSM - UNFIT", var= 'groupNUSM') Warning messages: 1: In approx(xx, xtime, seq(min(xx), max(xx), length.out = 17)[2 * : collapsing to unique 'x' values 2: In

Hello, I am new to R and have read the documents related to graphics but have not come across a description of how to change the maximum scale on a graph. Below is sample code that sets up a plot window with a 0 Minimum to 10 Maximum, X and Y coordinate system: x <- c(1,2,3,4,5,6,7,8,9,10) y <- c(1,1.5,2,2.5,3,3.5,4,4.5,5,5.5) plot(0:10, 0:10, type = "n" )# setting up coord.

Dear R mailing list, Greetings!!! I'm doing a graphical test of suitability for the aircondit data. I actually just followed the exercise in Davison and Hinkley's book of Graphical Test for model checking. The program for testing if it comes from an exponential distribution seems to be running okay but the program for the gamma distribution distribution is running away :-). I hope

A table without names displays like a vector: > unname(table(2:3)) [1] 1 1 1 and preserves the table class (as with unname in general): > dput(unname(table(2:3))) structure(c(1L, 1L), .Dim = 2L, class = "table") Does that make sense? R is not consistent in its treatment of such unname'd tables: In plot, they are considered erroneous input: >

Hello, I am working on a project to create some scatter plots. I have syntax for 26 plots, and 22 of them display as they should. But here, for example, is a sample of the command syntax I am using: good <- complete.cases(affect1,adh1scr) plot (jitter(affect1,2.0),jitter(adh1scr,1.0),xlim=c(1,35),ylim=c(1,35),pch=1 6, main='Adherence Score by Affectiveness Level - Visit 1',

Is there any way to use more than one color or shape in the same plot. I would like to make the points different colors for various levels of a variable. I have tried a simple 'if' statement in the plot command, but I get an error message. Here is what I have tried and the error message I get: > plot(test, if(test[,1]<8) col="steelblue2" else col="wheat2")Error
