How to add a common title (or xlab, ylab) for multi-plots in the same window?
Dear R people, I am using par(mfrow=c()) to plot multi-figures in the same window. And I like to put a common title (and xlab, ylab) for all of plots. I have already left some margin by resetting omi values in par() and hided all (xlab, ylab) for each sub-plot. Could anyone tell me how to do that? Thanks a lot, Frank

Write text in the
Hey Felix, So basically what you want is a figure containing a block of four plots, with a main title for the figure? If that's the case then something like this should work: # BEGIN CODE # par(oma=c(0,0,1,0), mfrow=c(2,2)) for(i in 1:4){ plot(NA,xlim=range(0,10),ylim=range(-5,5)) title(paste("Plot ",i,sep="")) } par(mfrow=c(1,1), oma=c(0,0,1,0)) mtext("Main

binary numbers
Hi, Is there a function in R that lets one represent an integer in binary format for a given number of bits? So an example would be.... > binary.function(num=5, num.of.bits=8) > "00000101" Or, is this something I have to write myself? Any help would be appreciated. Cheers, Sam.

p values when using rlm
R 2.0.1 Linux I am using rlm() to fit a model, e.g. fit1<-rlm(y~x). My model is more complex than the one shown. When I enter summary(fit1) I get estimates for the model's coefficients along with their SEs, and t values, but no p values. The p value column is blank. Similarly, when I enter anova(fit1) I get DF, Sum Sq, Mean Sq, but the column for F value and Pr(>F) are blank. Any

Noncentral dt() with tiny 'x' values (PR#8874)
Full_Name: Mike Meredith Version: 2.3.0 OS: WinXP SP2 Submission from: (NULL) (210.195.228.29) Using dt() with a non-centrality parameter and near-zero values for 'x' results in erratic output.

error bars
Hello R-help, I am using R version 2.15.1. I upgraded from R version 2.13 a few months back. Previously, I was able to plot error bars on an xy scatter plot using the errbar function: errbar(RAEthylene$TIME,RAEthylene$AVE,RAEthylene$AVE+RAEthylene$STD,RAEthylene$AVE-RAEthylene$STD,add = TRUE,lty=2,pch=17); Today, I went to update my plot. However, in R version 2.15.1 I get error code

Plots: displaying mathematical symbols in specific fonts
...nd, however, are not displayed in the desired font. For example, windows() plot(rnorm(15),rnorm(15)) text(0,0,expression(Delta),font=10) displays a capital delta, but it is not in font #10 within Rdevga. I can get characters that have one of the first 255 ascii codes using chars8bit() in the sfsmisc package. One example is the division sign: text(0,0.2,chars8bit(247),font=10) I have not been able to display other symbols in microsoft fonts, however. Is this possible to do in R? All replies are appreciated. -- Ed Merkle, PhD Department of Psychology Wichita State University Wichita, KS
