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.

...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 ?

...ing 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, 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

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 ?

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 attempting to place a title to a graph with multiple plots that should go across the top of all the graphs, and not just one of them. I am using mfrow in par to plot. Can anyone suggest if and how this could be done ? Thanks in advance, Tolga

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

Dear R-Users, Have a question about reading in some data and manipulating dates. I have a data set in excel which looks like this: Date PEG ETN HSP PTC 13/10/2004 41.92 64.75 29.86 9.27 14/10/2004 41.93 61.79 29.98 9.14 15/10/2004 41.69 62.7 30.09 9.04 18/10/2004

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.

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 ?

Dear R Users, I would like to get the pdf() command to create graphics in landscape mode, as I am plotting 8 graphs in 2 rows and 4 columns. This is being generated for an a4 printer (so I also use the paper="a4" command). Is there a way I can ask pdf() to generate the document in landscape mode ?
