Can anyone think of a way to create a pretty() sequence that excludes zero? Or a way to remove the zero from a sequence after using pretty()?

Hi all, This is a question for any of you who use R.app (OS X). Is there any way to resize the quartz plot window from within R? I know that you can resize the window by dragging the corner of the window, and fro the preferences panel. But is there a way to specify the window size from the console? I want to specify the size of the plot window from inside an R function. Also a

I am having trouble getting RMySQL working with R. It did at one point, work with an older 1.x version of R, but now with R2.2.1, I am getting the following messages on my OS X 10.4.5 system: RS-DBI driver warning: (MySQL mismatch between compiled version 4.0.24 and runtime version 4.1.14) if I then try to run any further db commands such as dbConnect, R crashes with a bus error. When

Can anyone tell me how to produce a macron (or overbar or overline) symbol on an R plot. I have an axis that is labeled "temp", but I need the overbar symbol over the entire word.

The manual entry for as.POSIX says this about time zone codes... Usage as.POSIXct(x, tz = "") tz A timezone specification to be used for the conversion... but it fails to mention what these "specifications" are. So far, I have tried... as.POSIX(x, tz="UTC") ... works, gives UTC times as.POSIX(x, tz="UTC") ... works, gives EST times as.POSIX(x,

Sorry to ask such a simple question, but I can't find the answer after extensive searching the docs and the web. How do you remove a component from a list? For example say you have: lst<-c(5,6,7,8,9) How do you remove, for example, the third component in the list? lst[[3]]]<-NULL generates an error: "Error: more elements supplied than there are to replace" Also,

I'd like to replace a value in a data frame with an NA, but can't figure out how. For example, say you have a<-c(1,2,3,4) b<-c(5,6,7,8) data<-data.frame(a,b) Now, how would you set the third row of the second column ( data [[3,2]] ) to NA? I have tried all types of permutations with is.na, including is.na<- data[[3,2]], which does not work. Thanks

Does anyone know how to get a vector of column sum from a data frame? You can use colSums(), but this gives you a object of type "numeric" with the column labels in the first row, and the sums in the second row. I just want a vector of the sums, and I can't figure out a way to index the "numeric" object. Thanks!

I have a vector of POSIX times/dates (called "times") that I want to plot. But I'm having trouble because R reports the length of the vector incorrectly. Can someone help me figure out what's going on here? This code.... print(times) print(class(times)) print(length(times)) Produces this... . . . [355] "2006-03-06 18:34:00" "2006-03-06 18:32:00"

Say you have a POSIX object that is in UTC. How do you change the values to another timezone? If I do this: times <- strptime(times, "%H:%M:%S") times1 <- as.POSIXct(times, tz="UTC") times2 <- as.POSIXct(times, tz="CDT6CST") times1 id UTC, but times2 is still UTC, not CTD. Why? Is the only was to change time zones to add seconds to POSIX objects?

Can anyone tell me how to select just one row of a data frame? Say I want just the third row, what would be the syntax? Every notation I try just gives me columns. Thanks - Jason

Hi there, Has anybody heard of a circular statistics packages/function collection in R (or S-Plus)? (I mean circular statistics for periodic data,(e.g., pointing directions), like the ones described in Batschelet (1980). For example used to compute mean angular deviation and variance, perform comparisons of mean angles using e.g. a Watson-Williams test etc.) I didn't find anything so far,

Dear List, I have circular data comprising direction and size for a number of observations. I wish to calculate statistics such as the mean direction and concentration for these data. I note that the CircStats package only deals with angular data (i.e. "Each observation is treated as a unit vector or a point on the unit circle". There appears to be no facility for weighting

I'm just starting to learn to use R, and although I'm seeing lots of functions aimed at doing orthodox statistical analyses, I don't see the same for Bayesian analyses. What support does R have for Bayesian statistics?

Hello, I just installed the above openssh onto a Sun Solaris 7 and Solaris 8 system. No problem with that. However, I now seem to get some rubbish processed when I login with slogin. An example: Last login: Tue Jun 13 12:31:27 2000 from jhorne.csd.plymo:tJ` ^[[?1;2c Telnet logs in okay, but just shows 'Last login...jhorne.csd.plymo'. This seems to get passed to the shell, which it of

Hello Friends!!! I would want draw a circular histogram, and I would like draw a polygon with a circular side. This is easy if I use the functions polygon and arc, but I want that the polygon with a circular side have background colour. The polygon created with function polygon can have background colour, but the surface created with function arc can?t have background colour. How I could create a

Attached is the patch I've been using to fix the error message seen in the subject line. It seems (!) to have caused no problems with the previous openssh snapshot version openssh-SNAP-20001016, 2.3.0p1 and the latest snapshot (openssh-SNAP-20001114). The patch adds 3 lines to nchan.c in a switch stmt (line 100). It simply caters for the cases where the input channel state is

In conducting studies of animal orientation and displacement, I need to produce circular histograms of angles (bearings in radians 0-2pi) where the centre of the circle indicates very few observations for a given bin of angles and outwardly concentric circles indicate greater frequencies of observations for a given bin of angles. I'd like not to have to write the function myself but I
