...(60,000 rows down) From my homework, the persp function only works with evenly spaced data points with the z data beeing in a matrix. my data is not in that format. the wireframe fxn gives me an error, no applicable method for "wireframe" the plot3d fxn I got working thanks to Scionforbai's help. However it does not represent the data like wireframe or persp would. Any help would be appreciated. thanks --------------------------------- [[alternative HTML version deleted]]

Hi, R-users, data is a matrix like this AMR BS GE HR MO UK SP500 1974 -0.3505 -0.1154 -0.4246 -0.2107 -0.0758 0.2331 -0.2647 1975 0.7083 0.2472 0.3719 0.2227 0.0213 0.3569 0.3720 1976 0.7329 0.3665 0.2550 0.5815 0.1276 0.0781 0.2384 1977 -0.2034 -0.4271 -0.0490 -0.0938 0.0712 -0.2721 -0.0718 1978 0.1663 -0.0452 -0.0573 0.2751 0.1372 -0.1346

Dear All, I am given a set of files names as: velocity1.txt velocity2.txt and so on. I am sure there must be a way to read them automatically in R. It is really taking me longer to read them than to analyze them. Anybody has a suggestion to help me out with this? Many thanks Lorenzo

Hello, R-devel seems to be the appropriated list for what I'm to ask: soory if I'm wrong. I am a c newbie but nevertheless I am trying to 'couple' an extern c software with R. The compiled library is actually a stand-alone c program, which uses text file for input and output. It uses *lots* of differents and (to me) rather complicated and nested "struct"s to represent

Hello, I am trying to find the analytical solution to this differential equation dR/dt = k1*(R^k2)*(1-(R/Rmax)); R(0) = Ro k1 and k2 are parameters that need to fitted, while Ro and Rmax are the baseline and max value (which can be fitted or fixed). The response (R) increases initially at an exponential rate governed by the rate constants k1 and k2. Response has a S-shaped curve as a function

Hey Seniors, Really new to R, please has anyone imported a dataset from MS office excel 2007 into R yet? It seem to be giving me hard times which I did not expect as it use to go well with the previous versions. Thanks in advance. arnoldo --------------------------------- [[alternative HTML version deleted]]

Hi, I'm trying to use expression() to write a text to a graphic in the margin. Using: mtext(expression(beta),side=1,line=2) writes a perfect beta greek character, but I need to add a subindex "max", and I'm trying: mtext(paste(expression(beta),"max"),side=1,line=2) simply writes "beta max" in the plot. Please, Could you tell me what I'm doing wrong?

Hi, Let us suppose I have a list x = list () x $ name1 = 1 x $ name2 = 'a' in the work environment. Let us suppose that in the body of a function I want to acces to a component of x by using its name as argument of that function. How can this by done? For instance, I was expecting f = function ( name ) x $ name to output 1 ( that is, x $ name1 ) when I command f ( name1 ) or f (

Dear R-users, I wonder whether it is possible to speed up plots of 2-dimensional images (such as image() or levelplot()) in order to export lower quality versions of the resulting plots. I intend to export a large number of images in order to construct animated gifs. For this purpose, I used the png()-function in conncection with image() and levelplot(). But the underlying arrays are so big

Dear R users, My question is that how it is possible to generate some random numbers using rnorm( ) function but in log transformed values. Thank you, Tobias --------------------------------- [[alternative HTML version deleted]]

Hello All, I am a newcomer to R. Currently, I am trying to write an interactive code in R to let it read the equation which I write and execute the equation in a curve function. For example: I want to plot curve by using: curve (equation, -2,2, n=1000) what I want is that the R code ask me what equation I want to use (which I know how to write this code): then, I type for example 3*x. then 3*x

I am trying to dp a 3d plot. I tried persp but my data is not a matrix. the 3dplot function returns this error, (list) object cannot be coerced to 'double' heres my code, td<-read.csv("td.csv", header=TRUE) price<-read.csv("price.csv", header=TRUE) contractdate<-read.csv("contractdate.csv", header=TRUE) library(rgl)

Dear list, I have to plot some geometrical shape given as list of points. My need is the following: let's say my shape is a 1 inch large square; how can I plot it with R in a graphic format that gives me an image *exactly* 1 inch large? I tried to set oma, mar and fin parameters, but with no success. I'm currently using the xfig driver for the final images are to be included in latex

Hi all! I have lots of functions called in the following pattern 'NameOfFunctionNumber' where the name always stays the same and the number varies from 1 to 98. Another function which I run in advance returns the number of the function which has to be called next. Now I want to combine 'NameOfFunction' with the 'Number' returned so that i can call the desired function. I

Using Tinn-R (in windows) is possible to run latex and R from the same editor, which was great. Now, I am using Ubuntu-linux, which has been better than WinXP. Currently, I am using Emacs (and then install ESS) for running LaTeX and R from a same editor-program (like i was doing with Tinn-R in windows). Nevertheless, and even though i have been using Emacs for almost 2 years, it is not as

I want to run a R program, prog.R, interactively. My question is, is there a way I can start prog.R on the shell terminal when invoking R, instead of using source() inside R? TIA, Gang
