I would like to know how to convert a string with characters to all uppercase or all lowercase? If anyone could let me know if there exists a function in R for the conversion, that will be very helpful. Regards, Suman [[alternative HTML version deleted]]

I am using R on unix. While in R how do I execute the unix shell commands? Is there a way to do it? I am executing a function in R and the matrix resulting from the function has to be passed on as an input to unix command. Any directions will be helpful.

Hi, I wanted to know how to compute the correlation ratio (eta) between two variables using R. Is there any function to compute the correlation ratio. Any help will be very much appreciated. Thanks, Suman [[alternative HTML version deleted]]

I need help with calculating lsmeans (adjusted means) of different terms in a linear model including the main effect and the interaction effect terms. I use lm to run the linear models...I previously noted from literature that that "effects" package can be used to generate lsmeans. But I tried to use it but could not figure out which option to use to get means. If anyone can give an

Hello, I have a big matrix of size (20,5) -bmat . I have to loop though the rows in the matrix and create DIFFERENT matrices each time I go through the loop. counts=c(4,6,10); p=1; for (i in 1:length(counts)) { smat=bmat[p:p+i-1,]; p=p+i; } The problem is smat overwrites itself each time inside the loop. I would like to have smat1, smat2, smat3 instead of a single vector smat.

Hello, This might be a very basic question but I was not sure how to go about it. I just wanted to calcluate the time it takes to run my program. Basically I was to put a timer at the start and the end of the program in order to see how much time it takes to give the output (similar to tic-tac in MATLAB) . Any help will be appreciated.

Hello, I have a dataset with 20,000 variables.and I would like to compute a pearson correlation matrix which will be 20000*20000. The cor() function doesnt work in this case due to memory problem. If you have any ideas regarding a feasible way to compute correlations on such a huge dataset, please help me out. Please feel free to share your memory handling techniques in R. Thanks, Suman

Hello, Below is some example code that should reproduce an error I'm encountering while trying to create a tiff plot with two subplots. If I run just the following bit of code through the R GUI the result is what I'd like to have appear in the saved tiff image: x<-seq(0:20) y<-c(1,1,2,2,3,4,5,4,3,6,7,1,1,2,2,3,4,5,4,3,6) plot(x,y,type="l",las=1,ylim=c(0,12))

Hi, I've run into a difficulty with qplot function (in the ggplot2 package). I can facet histograms even when the faceting variable contains missing values, but only so long as the faceting variable is not a factor. Example: y1 <- rnorm(10) x1 <- c(rep(1,5), rep(2,4), NA) x2 <- factor(c(rep(1,5), rep(2,4), NA)) library(ggplot2) qplot(y1, geom = "histogram", facets =

Hello, I wanted to know how to plot a histogram using a vector of frequencies rather than the data vector as a whole. So I have two vectors: a vector of labels V1= c("A","B","C","D") and vector B which is a vector of frequencies of A, B, C and D respectively V2=c(20,50,60,30). I wanted to plot a histogram of the labels using the frequencies. I could not

In lattice #toy data library(ggplot2) library(lattice) x <- rnorm(100) y <- rnorm(100) k <- sample(c("Weak","Strong"),100,replace=T) j <- sample(c("Tall","Short"),100,replace=T) w <- data.frame(x,y,j,k) xyplot(y~x|j+k,scales=list(y=list(relation="free"))) will give you a scale in each subplot with a range equal to the range of y

I want to draw a little subplot ("overview") into my detailed plot. It should be placed in say the top right corner and have the size of some legend (like legend(x="topright", inset=0.03, ...) #main plot plot(rnorm(100)) #give little density in corner plot(seq(-2,2,length=300),dnorm(seq(-2,2,length=300)),type="l") I don't want something like par(mfrow=c(1,2)) as

Hi, I'm trying to get a color-gradient triangle out of a large plot. Wonder can subplot() generate a triangle? So far, I'm only getting rectangles. Great appreciation for any reply!! Kexin

Hi, I making a figure with six sub-plots using par(mfcol=c(2,3)). In the last sub-plot I want to have two graphs instead of one. I have tried using par(fig=x,y,z,v) but this par seems to overwrite the first par. Is there a simple solution? Thanks!

Folks, I am having problems with a plot I want to create to give an impression of changes in an ordinal scale measure (1-5) at three time points (0, 14 and 21 days). I can produce a radial plot of bare vectors but getting this to appear on the base plot is not possible as it always seems to end up below the plot area and even outside the plot window. It seems I have not understood

Hi, I wish to plot multiple histograms(representing different data so different range along xaxis but y axis is the same) horizontally in ggplot2. I'd like it to look like facets. Is this possible? -- Rajesh.J [[alternative HTML version deleted]]

Hi all, Is there a way to rotate a plot, e.g. a histogram, by a certain angle (90/180/270 degress)? I spent hours trying to figure out how this is done, but without success. Also, I'm looking for an equivalent to the S-Plus "subplot" command to insert a kind of "thumbnail" graphic into a bigger one. How is this best done in R? Thanks for your help Pascal

Dear R-gurus, Is there any function in R does the same thing as function subplot()in Splus? I am trying to post a pie chart onto the top right hand corner of existing bar chart. Also, Does anyone know if I can use paste() to paste the graph to another graph? Cheers, Carla Chen

Dear All, After having overcome the issue of legends (thanks, Thierry, once more), I am trying to use facetting, but here also I can not find how to do this. I do not want to use qplot, but rather the more flexible options. However, it seems I am doing still something pretty stupid, because I always get an error, even if it seems I am doing everything like the examples. My code is below.
