similar to: Title for graph with multiple plots

I have a 2x2 plot set up using: par(mfrow=c(2,2)) I'd like to put an overall title on the page, but I cannot figure out how. Any ideas? [[alternative HTML version deleted]]

Hi, I plotted 12 graphs on a page and output to a png file. I wanted to have an overall title for all 12 graphs. What command can I use to do this? Below is the code that plotted the 12 graphs in one page. # FM10 by Month/ Export the plot to Wash2005FM10.png png(file="Wash2005FM10.png",bg="white") par(mfrow = c(3,4)) # Plot 12 Month of OFM10, FFM10 for(i in

Dear R Users, Does anyone know of a package which can generate random realisations of a double-exponential jump diffusion process with a drift ? Something where I can specify the likelihoods of an up or a down jump, the drift rate, and the mean size, and get back a vector of realisation of the process (for purposes of a Monte-Carlo). Kind regards, Tolga

Dear R Users, I am trying to get plot.zoo to place monthy tickmarks/labels for a time series which spans daily data going back a bit over a year. Right now, I am getting only one tick mark on the x-axis for the beginning of 2008. How can I force plot.zoo to place more regular x-axis tick marks on a monthly basis ? Thanks in advance, Tolga Generally, this communication is for informational

Hi, Am sure this is a trivial question but for some reason, haven't been able to figure it out. I want to bucket data in a vector, and then iterate over the buckets. Say the data set is: > cleandata[,4] [1] 26 26 26 26 26 26 26 26 26 26 26 26 61 61 61 61 61 61 61 61 61 61 61 89 89 89 89 89 89 89 180 180 180 180 362 544 544 544 [39] 544 544 544 544 544 544

Dear R Users, I am working in an environment in which I am not able to compile any code. Sad, but true. Is there a Windows 32-bit version of 2-15.2 anywhere ? I am currently unable to use packages Matrix and mgcv because they appear to have been compiled for 2-15.2 but only 2-15.1 is available for download from the regular CRAN websites.

Dear R Users, I would like to plot three time series on the same graph, two axis on the left and one axis on the right. The time series that I am graphing on the left do not share a similar scale: one has a range of 1:100 and the other a range of 25000:70000. How can I display the tick marks for both on the left hand side without superimposing them, i.e. one set of tick marks in black right

Hi, I am trying to plot multiple lines on a graph. The function is particularly simple: sigma<-function(lambda) atm-2*rr*(lambda-0.5)+16*str*(lambda-0.5)^2 which uses the variables atm, rr and str... I define these as such: atm<-0.4 rr<-0.2 str<-0.1 and this plots fine: plot(seq(0.01,0.99,0.01),sigma(seq(0.01,0.99,0.01)),ylim=c(0,1)) Now, I want to plot the same function for

Hi there, Is there an implementation of the Gaveh Stehfest algorithm in R somewhere ? Or some other inversion ? Thanks, Tolga

Hi, Is there a way to send an ESC command to the console from within a script window, without using the mouse ? Thanks, Tolga

Dear R-Users, I am looking for a way to get legends placed automagically in an empty spot on a graph. Additional complication comes through my useage of multiple graphs on the same plot through mfrow. Is there a way to achieve this in R ? I have legends for each of the sub-plots.

Dear R Users, I am on Windows XP SP2 platform, using R version 2.7.2 . I was wondering if there is a way to find out, within R, the number of CPU's on my machine ? I would use this information to set the number of nodes in a cluster, depending on the machine. Sys.info() and .Platform do not carry this information.

Hi, Suppose I have an arbitrary function: arbfun<-function(x) {...} Is there a robust implementation of a numerical derivative routine in R which I can use to take it's derivative ? Something a bit more than simple division by delta of the difference of evaluating the function at x and x+delta... Perhaps there is a way to do this using D or deriv but I could not figure it out.

Ah... I searched for half an hour for this function... you know, the help function in R could really be a lot better... But wait a minute... looking at this, it appears you have to pass in an expression. What if it is an unknown function, where you only have a handle to the function, but you cannot see it's implementation ? Will this work then ? -----Original Message----- From: Berton Gunter

Dear R-Users, I've written a number of functions in a .R/script file. I would like to call those functions from another script file. How can I execute all the code in a script file so that the functions are available for use in my other script file ? I have tried help.search("script") and various Google alternatives but couldn't come up with anything. Thanks in advance,

Hi, I defined corr to be a function, not realising that this was also the name for correlation in package=boot. How do I explicitly call the corr function within package boot (so, scope up over the current frame, I guess is another way of saying it) without removing my new corr function ?

Dear R Users, A bit of a simple question, but I could not find the answer thru google ("sorting lists r cran","how can i sort a list r cran") or RSiteSearch... how can I sort a list ? One imagines something like sort.list would do the job, but that's not the one. > foo<-list(a=10,b=2,c=3) > sort.list(foo) Error in sort.list(foo) : 'x' must be atomic

Dear R Users, A bit of an elementary question, but somehow, I haven't been able to figure it out. I'd like to changes the column names of a data frame, so I am looking for something like col.names (as in row.names). Could someone please show me how to change the column names of a data frame ?
