similar to: pch=NA in bxp.Rd (PR#8073)

I'd like to suggest changes to three help pages, regarding the use of pch=NA to suppress plotting symbols. See below. Arni R 2.0.1 on WinXP === help(bxp) === The argument outpch=" " needs to be replaced with outpch=NA in two places. I actually wrote this part of the documentation myself at one point, but have now realized that pch=NA and pch=" " are not the same:

Dear r-bugs, I'd like to be able to draw boxplots with solid or dotted whisker lines. The lty argument is currently ignored by boxplot(), and indeed hardwired in bxp(). It's not very difficult to customize these functions to generate various types of boxplots, but generally it might be an idea to allow the user to pass a few more graphical arguments to boxplot(). The approach might as

Hi, I was just trying to figure out how to beautify the output of my bwplot-output. Altogether I figured most of the things out on my own. The one thing which puzzles me though are the symbols for the outliers. I can easily change the form of the median symbol by using "pch" but I don't know how to do this for outliers. Obviously the "outpch" of the

Full_Name: Steve Ellison Version: 2.4.1 OS: Windows, Linux Submission from: (NULL) (194.73.101.157) bxp() allows specifcation of box locations with at=, but neither adjusts xlim= to fit at nor does it respect xlim provided explicitly. This is because bxp() now includes explicit xlim as c(0.5, n+0.5), without checking for explicitly supplied xlim (or ylim if horizontal). This also prevents

It's not new anyway. You see the same behaviour with boxplot(dat, ylab=quote(X[2])) and it boils down to the use of do.call("bxp", ...) in the internals. As a general matter, expression() exists to prevent this sort of confusion, e.g., in this construction, > X <- quote(Y+1); bquote(f(.(X))) f(Y + 1) is indistinguishable from just entering f(Y+1), so f has no way of

What is mystifying is that the issue was not present in previous versions, = so appropriate code already existed. However, I agree that there seem to be a couple of additional issues that = I had missed. =20 I am perfectly happy to look at this again myself, though, and provide = extended code; would that help?

The weighted.mean() function replaces NA values with 0.0 when the user specifies na.rm=TRUE: x <- c(101, 102, NA) mean(x, na.rm=TRUE) # 101.5, correct weighted.mean(x, na.rm=TRUE) # 67.66667, wrong weighted.mean(x, w=c(1,1,1), na.rm=TRUE) # 67.66667, wrong weighted.mean(x, w=c(1,1,1)/3, na.rm=TRUE) # 67.66667, wrong The weights are

The write.csv() function is currently implemented as function (..., col.names=NA, sep=",", qmethod="double") { write.table(..., col.names=NA, sep=",", qmethod="double") } Surely, it should be function (..., col.names=NA, sep=",", qmethod="double") { write.table(..., col.names=col.names, sep=sep,

This relates to a message from Christophe Pallier to r-help some time ago. Like myself, he finds aggregate very useful, but the interface a little cumbersome. I've implemented a more compact formula interface, found at the bottom of this message: data(ToothGrowth) # I used to aggregate like this: aggregate(list(len=ToothGrowth$len),

I present you with a function that solves a problem that has bugged me for many years. I think the problem may be general enough to at least consider adding this function, or a revamped version of it, to the 'stats' package, with the other multinomial functions reside. I'm using R to export data to text files, which are input data for an external model written in C++. Parts of the

Hi all, I have been previously been using scatterplot3d package to create some graphs but unfortunately it does not allow me to rotate the plot on all three axis. The cloud() function in the lattice package does allow me to do so. When I was using scatterplot3d I was using a script (Shown Below) to calculate the mean, quartiles and range limits for all three axis and I was representing that on the

One descriptive statistic that is conspicuously missing from core R is the statistical mode - the most frequent value in a discrete distribution. I would like to propose adding the attached 'statmode' (or a similar function) to the 'stats' package. Currently, it can be quite cumbersome to calculate the mode of a distribution in R, both for experts and beginners. The lack of a

Dear r-bugs, The 'see also' link in help(area,html=T) is broken, see line 91 in library/MASS/html/area.html: "../../integrate/html/integrate.html" should be "../../base/html/integrate.html" Regards, Arni OS: Windows XP R: 1.7.1 MASS: 7.1-8

In Windows XP, the matrix() function crashes the program when 'dimnames' is an empty list: matrix(1:4, nrow=2, dimnames=list()) # R has encountered a problem and needs to close ... This bug is specific to WinXP, as Linux64 handles this situation more gracefully: matrix(1:4, nrow=2, dimnames=list()) Error in matrix(1:4, nrow = 2, dimnames = list()) : invalid type

Hi All, As a follow-on from the mail below, it is possible to have boxplots based on means and variance for more than one input, i.e., bxp(input1,input2,....)
