hello, you can use the persp() function. The shade=0.7 option is very nice. With matlab, it is possible to change of colors automaticalli with the value to be plotted. Does someone know to do that ?

Hey, R-listers I was recommended to try using smooth.spline function for estimating 2-Dimensinal curve given a data set. So will you please tell me where to get this R function? Or which package provides this function? Thanks for your point. Fred

Hey, All In principal component analysis (PCA), we want to know how many percentage the first principal component explain the total variances among the data. Assume the data matrix X is zero-meaned, and I used the following procedures: C = covriance(X) %% calculate the covariance matrix; [EVector,EValues]=eig(C) %% L = diag(EValues) %%L is a column vector with eigenvalues as the elements percent

Hi, R-listers I tried to plot several graphs in a sigle x-y coordinate settings, like the following: |(y) s | ****** s | ***** s | sssssssssssssssssss |_______________________________(x) where "*" and "s" denote two diffrent plots. However, when I used plot(data1); % data1 is the data points of "*"

Hey, I want to draw several plots sequently, but have to make them dispaly in one figure. So how to achieve this? Thanks. Fred

Hi, R people. Consider the following small R session: ======================================================================> > a <- c(8.48, 9.58, 9.96) > stem(a) The decimal point is at the | 8 | 8 | 5 9 | 9 | 6 10 | 0 > stem(round(a,1)) The decimal point is at the | 8 | 5 9 | 9 | 6 10 | 0

I would like to do some fairly basic stem-and-leaf displays in R. I am aware (I might even say painfully aware) of stem(base) and have tried it. That's why I'm hoping someone has a usable stem- and-leaf display for R so that I don't have to write my own. r-project.org > Search > R Site Search > "stem and leaf display" finds nothing. I also tried the mail archive

I must apologize in advance for asking a simple question. I am sure that a clue will be sufficient to get this show on the road. I am trying to graph tide prediction data in various ways. I haven't been able to answer this question after pouring over TFM. I read the datafile theight <- read.table("tides",header=TRUE) I do get a summary() or fivenum()

On https://projects.centos.org/trac/stem/ there is a brief mention of Stem and VOIP with a request for dial-in numbers. However there are no links on the page describing STEM. Stem sounds a bit like the Dutch word for 'voice'. What type of dialing-in, from the PSTN, numbers are required and how can they be used to benefit Centos? -- With best regards, Paul. England, EU.

Hi, I would like to make a stem and leaf plot and I want to edit the category-names. So, by doing this: > x <- c(1,2,2,3,3,3,3,2,2,1) > stem(x) I get: 1 | 00 1 | 2 | 0000 2 | 3 | 0000 First Question: Why do I get gaps between the categories? (like in line 2 and line 4) And second: How can I edit the categories so that I can create something like that:

Hi R is open source so you could dig into the code. However the actual stem function is probably written in C, so it is beyond my expertise. If you replied to the list there could be experts who are able to provide explanation. > stem function (x, scale = 1, width = 80, atom = 1e-08) { if (!is.numeric(x)) stop("'x' must be numeric") x <- x[is.finite(x)]

Is the following a bug with stem() or is there something else that I am missing? I ran stem() on the vector x below and got stem(x-10) instead of stem(x). If I subtract 1 from x, I get a correct answer. If I add 1 to x, I still get a wrong answer. If I add 10 to x, I get a correct answer. I'm not sure what to make of this, other than to think it is a bug. Can anyone tell me if this is a bug?

Hi All I came across a problem below when doing stemming and stem completion with package tm in R. Word "mining" was stemmed to "mine" with stemDocument(), and then completed to "miners"with stemCompletion(). However, I prefer to keep "mining" intact. For stemCompletion(), the default type of completion is "prevalent", which takes the most

Hi there, I am trying to find a way to accomplish parallel stem-and-leaf displays in R, yet there seems to be no specific command nor info in the archive that I can depend on. Specifically, there are two batches of data that I want to put together in parallel stem-and-leaf displays. Would anyone help me figure out how to do this in R? Thank you sooooooooooooo much!
