similar to: Bug in boxplot(..., add=TRUE) ?

Dear all, I am trying to create a web interface using Perl-CGI to call R plots and to display them. The following codes works perfectly fine when I copy and paste into the console directly or if I save it into script.file and then R --no-save < script.file producing the graphs. jpeg("graph.jpeg", width=400, height=400) plot(rnorm(100)) dev.off() Now, I put the line system("R

Dear list, Utils::modifyList() drops NULL components in its second argument, instead of adding them to the first argument. Compare: > modifyList(x=list(A=1), val=list(B=2, C=3)) $A [1] 1 $B [1] 2 $C [1] 3 > modifyList(x=list(A=1), val=list(B=NULL, C=3)) $A [1] 1 $C [1] 3 To me this seems inconsistent with the documentation ("Elements in 'val' which are missing from

I am using R 1.7.1 on Windows XP Pro. The 'overwrite=FALSE' argument appears to be ignored in file.copy(): > file.exists(c("file1.txt", "file2.txt")) [1] TRUE TRUE > file.copy(from="file2.txt", to="file1.txt", overwrite=FALSE) [1] TRUE > and sure enough, file1.txt has been overwritten.

R 1.7.1 on Windows XP The "normal Q-Q plot" produced by plot.lm() mislabels points when the model is fitted using na.action=na.exclude. Example: x <- 1:50 y <- x + rnorm(50) y[c(5,10,15)] <- NA # insert some NA's y[40] <- 50 # add an outlier plot(lm(y ~ x, na.action=na.omit)) # outlier correctly labeled in all # four plots

The following command, temp <- read.table("c:/rfr/r/test.txt") reads the text file "test.txt", which contains the following lines: 21437 21438 21419-2 21420-2 21421-2 21422-2 and produces the following result: > temp V1 1 21437+0i 2 21438+0i 3 0+0i 4 0+0i 5 0+0i 6 0+0i > These "numbers" are actually sample ID's, and I

Hello, I have created two boxplots with following R code. There is one outlier in B group. The outlier is 33. But the all other data are between 0 to 4. How can I skip y-axis around 5 to 25, and expand 0-4 for this case. Also I want keep the outlier in my boxplot. I want my boxplot look like the second one, keep the outlier, and make an interrupt of y-axis from 5 to 25. Thanks, Jianghong

#Example: y <- rnorm(10) group <- gl(2,5) plot(y ~ group, horizontal = TRUE) # BUG: default xlab & ylab interchanged plot(y ~ group, horizontal = FALSE) # OK: supplies correct default xlab & ylab # Using boxplot() instead of plot() omits default axis labels altogether # (not sure if this is intentional): boxplot(y ~ group, horizontal = FALSE) # no default axis labels supplied

A function I've been using for a while returned a surprising [to me, given the data] error recently: Error in plot.window(xlim, ylim, log, asp, ...) : Logarithmic axis must have positive limits After some digging I realized what was going on: x <- c(10460.97, 10808.67, 29499.98, 1, 35818.62, 48535.59, 1, 1, 42512.1, 1627.39, 1, 7571.06, 21479.69, 25, 1, 16143.85, 12736.96,

I don't see any reference to legends in the documentation (so I suppose the answer is no?). Although the documentation says image takes plot() parameters, it isn't clear to me how the usual use of legend in a plot command

Hi, the graphical parameter "cex.axis" does not have any affect for "boxplot": data(iris) boxplot(iris[,1:4], ylab="y", cex.lab=2, cex.axis=2) The patch is simply adding "cex.axis" to the search for axis relevant parameters in "bxp": ax.pars <- pars[names(pars) %in% c("xaxt", "yaxt", "las",

Dear all, I would like to (i) produce boxplot graphs with axis in logarithm in base 10 and (ii) showing the values on the axis in 10^exponent format rather than 10E+exponent. To illustrate with an example, I have some widely spread data that I chart plot using boxplot() [figure on the left]; the log="y" option of boxplot() I obtained the natural logarithm conversion of the data and

Hello, I am making a boxplot of 13 boxes. I tried to color the box using 13 colors but failed. Only red and brown were displayed. Green, blue, and grey disappeared. Please kindly advise modification after checking the code below. Thank you in advance.

Dear R-users, I'm a bit of a rooky in R and do not know how to change the y-axis intervals of a boxplot. The y-axis in my boxplot ranges from 0 to 100 which is fine. The problem is the interval level in between. Now it increases with steps of 20 but I'd like to have it changed by steps of 5. Anyone knows how to do this in R? I used the following code for producing this boxplot:

I'm graphing a series of boxplots of grouped data inside a function that passes the data.frame, the names vector, and a title vector. Because both the data subset changes with each successive pass through the function, occasionally the names vector turns up with only one group to plot. This is an expected result. However, when the names argument in boxplot has only a single name, it

Dear, I am a newbie to R. Now I am learning to draw boxplot using graphics(). I want to highlight the median position with a round point and the value left (or on the top of)to the point. Please kindly share the command and thank you. Elaine [[alternative HTML version deleted]]

Full_Name: Bob O'Hara Version: 2.6.0 OS: Windows XP Submission from: (NULL) (88.112.20.250) Using horizontal=TRUE with boxplot() confuses it as to what is an x- or y-axis. At least, xlim= and ylim= are the wrong way round, log="x" (or "y") and xaxt= work as expected, I haven't looked at anything else. Some code to see if you can reproduce the bug (or discover

R 3.5.1 on Windows 7 The documentation for 'var' says: "These functions return 'NA' when there is only one observation (whereas S-PLUS has been returning 'NaN'), and fail if 'x' has length zero." The function 'sd' (based on 'var') has similar documentation. However, I get: var(numeric(0)) [1] NA rather than an error. Personally I

I'm trying to write a package which uses classes/methods as defined in the `methods' package. I have a single .R file which defines the class and various methods for that class. At the top of the file I have require(methods) and then setClass("myclass", ...) setGeneric("intersect") setMethod("intersect", "myclass", function(x,y) ...) I noticed

r-help, I can't seem to get the below data organized in such a manner so as to generate a contour plot using any of the functions {lattice.contourplot, base.contour, base.filled.contour}.
