Hello, I am trying to display some harmonic functions in a plot. The kind of display I have in mind is like the one that cn be obtained by a call to plot.ts with plot.type = "multiple". The only difference is that I want a single box containing all the plots instead of one box per plot. I thought box(which = "outer") would have done the job, but it didn't. Below is the

Hi all, I have this code I want to add two ablines like this abline(h=2400, lty=3, col="lightgrey") abline(h=400, lty=3, col="lightgrey") But doesnt wotk.

Hello, I plot box plot, and add a point to the box indicating mean. I also add some range to the box width. I want to add legend for both the range (line) and mean (point). However, I cannot add line legend and point legend together. The code looks like the following. (1) First, I tried the following code, however, it plot a line across the point legend("*"). boxplot(count ~ spray,

Problem: neither fg or bg nor color work properly in dotchart. version: R-1.7.1 for windows code which shows the errors: x <- matrix(rnorm(16),ncol=2,dimnames=list(paste("a",1:8,sep=""),c("before","afte r"))) dotchart(x,fg="blue",bg="lightgrey") dotchart(x,color=c("red","blue")) Dr Ian J Wilson Lecturer in

In the example R script below, horizontal gray gridlines are drawn at y coordinates where the points are drawn with the code: panel.abline(h=y, v=xScale, col.line="gray") How do I change this so that the horizontal gray gridlines are drawn at y coordinates where the y labels are drawn? The challenge is that each panel has different y-ranges (in my real example the y-ranges and

dear all, a simple question, I need to write a function in which I retrive an undetermined number of vector in the function. I solved the problem thanks to this link http://stackoverflow.com/questions/2540232/how-to-allow-multiple-inputs-from-user-using-r so my function will look alike this my_fun <- function(...){ my_list <- lapply(..., function(x){x}) } I need just one more

Hello, I am using xyplot and am happy with my graph, *except* that I cannot get the symbols to be filled. I tried using bg=c("red3","red","black","lightgrey")) in both the key and the xyplot function, that that was obviously not the answer. I would like the sybols to be filled with the same colors as the lines. Does anybody have an answer? In case

Hello, I appreciate this is likely to be an easy question. I am trying to obtain the residuals from a linear regression where the line is forced to have a 1:1 relationship. An example of the data: A<-c(0.9803922, 1.3850416, 0.8241758, 0.0000000, 0.4672897, 1.1904762, 0.0000000, 0.9456265, 1.5151515) B<-c(1.3229572, 1.9471488, 1.3182674, 0.7007708, 1.0185740, 1.0268562, 0.8695652,

Hello, I am a beginner with R and I would need some help with doing barplots. My problem is that I would like to include both diffrent colors of the bars and precence/absence of shading lines in the barplots. When reading in the help file about the "col" command it states: col: a vector of colors for the bars or bar components. By default, grey is used if 'height'

The pretty picture that I saw at: http://chartsgraphs.wordpress.com/2009/02/09/r-panel-chart-beats-excel-chart/#more-1096 inspired me to try something similar.

dear all, we am trying to improve the performance of my R code, with the implentation of some function with custom C code. we found difficult to import and export/import data structure such us matrices or data.frame into the external C functions. we already tried the solution from "Writing R Extensions" form the R webpage. do you have any other solution or more advanced documentation

Hi, I want to get a histogram with the legend for my data. I drew a normal density curve and kernel density curve in the histogram, and I also label mean and median in the X axis. From the code, I got two legend: One shows "Normal Density" and "Kernel Density" and their corresponding lines, the other shows "Mean = value" and "Median = value" and their

Hi all, I would like to add to each panel of a bwplot a coloured central band, centered on the mean of the values, being its width +- 2% of the mean itself. I know how to add lines, i.e. something like bwplot(X ~ Y|FACTOR data=my.df, panel= function(x, y){ panel.bwplot(x, y) panel.abline(v = mean(x, na.rm = T) - mean(x, na.rm = T) * 0.02 panel.abline(v =

Hi All. I'd like to programm a 4 dimensional chart in R. Acctually I wanted to solve that problem in Excel cause I had the data there. Here is a link of my actual problem description (there are some chart pictures as well).... http://www.mrexcel.com/board2/viewtopic.php?t=187336&highlight=stacked+column because I still couldn't solve that problem I came to R.

I have a dataset with transactions and a timestamp at which they occoured during a day. The time stamp is in the format YYYY/MM/DD hh:mm:ss. I would like to plot a timeseries of the transactions to see if there is a particular time in the day when there is a spike in transactions. Ofcourse the YYYY/MM/DD can be dropped since I am monitoring activity for the day and the actual date is

hi BioC, I need to plot a vector of characters on a pdf device, not as a legend, but as in image by itself. I tried text but it is only related to locate text in a plot. what do you suggest? > sessionInfo() R version 2.6.0 (2007-10-03) x86_64-unknown-linux-gnu locale:

Hi R-users, I'm new to R and I'm trying to make a barplot combined with two lines (refering to secondary y-axis). Bars should represent the number of transfused patients by age class and sex and lines should represent the amount of blood units given in age classes. I have now successfully made a barplot and used par(new=TRUE) to plot another empty graph at the top of the barplot.
