Hi, Here's the data we have: > rs[1:5,] probe_id f1 f2 f3 f4 M A f 1 A_68_P20002076 2 58 0 0 1.51778114 6.344453 59 2 A_68_P20002775 22 8 15 0 0.43419304 5.488819 59 3 A_68_P20005791 43 3 0 0 0.05698666 9.830594 59 4 A_68_P20005805 11 34 0 0 1.71076835 6.624038 59 5 A_68_P20006729 16 44 0 0 0.85498261 6.044229 59 I want rs$f be the max of f1, f2, f3,

I'm trying to use combine c('a','b','c','a','c') into 'a, b, c', the order does not matter. paste(c('a','b','c','a','c'), collapse=', ') yields 'a, b, c, a, c'. Any idea? -- Regards, Anh Tran [[alternative HTML version deleted]]

Hi all, What parameter should I feed to the hist function to draw a line, not bar graph for a histogram? Smoothed line would be great too. I've looked at curve() for normal distribution but it's not what I need. I need some curve on top of the histogram (fit to the actual data). Just as a way to illustrate, rather than bargraph. Thanks -- Regards, Anh Tran UCLA NeuroOncology Lab

Hi, Is there away to print a short table out along side with a plot? I'm thinking about doing a par(mfrow = c(1,2)) Then, the plot is on one side, summary result on the other. Is there any quick way to print out a data.frame in table format? Thanks -- Regards, Anh Tran [[alternative HTML version deleted]]

Hi all, I'm putting a few plots together and wondering what format would be best to export a few scatter plots to Illustrator to make a figure. I'm thinking about overlaying some plot in Illustrator, so the export file type has to be transparent for Illustrator (version 10). I tried PNG and TIFF, but it does not seems to have transparency that is recognized by Illustrator (or Photoshop for

Dear R users, I am new to Latex and I am using the R package xtable to generate tables. I want to produce a table that is very long. in the landscape format, but I would need to rescale the table so that it fits in the page. xtable enables me to have the landscape format, but I cannot rescale it, and there seems to be a problem, if I use scalebox in Latex on my output produced with stable and the

Dear all, I am trying to create a 6-plot layout - 3 rows and 2 columns - so that only the top two plots have variable widths, all else with their default setting. Using "layout(matrix(c(1,2,3,4,5,6),3,2,byrow=T),widths=c(5,2))" rescales column #2 of all three rows, whereas I would like to rescale that of only row #1. Is there a simple way of doing this? Thanks, Manojit

Full_Name: Gerhard Thallinger Version: 2.3.0; 2.2.0 OS: Windows XP Submission from: (NULL) (212.183.54.87) Invoking windows() with the parameter rescale="fixed" followed by plot.new() or any other plot command causes very often the following error: windows(width=7, height=7, rescale="fixed");plot.new() Error in plot.new() : outer margins too large (fig.region too small)

Dear Rusers, Recently, i saw the sentence "rescale the data into unit square" for several times. Could anybody tell me what it means,and give an example? Thanks very much! -- Kind Regards, Zhi Jie,Zhang , [[alternative HTML version deleted]]

I am trying to run the R Script below, I have actually simplified it to just this part that is causing issues. When I run this script I continue to get an error that says "cannot rescale a constant/zero column to a unit variance". I cannot figure out what is going on here. I have stripped down my data file so it is more manageable so I can try to figure this out. The data.txt file

If these things bother you, could you please supply fixes? For some reason you omitted the part of the help page dealing with one of these (which is as documented), and I also think you are confusing `plot' and `device' sizes. The latter will be the displayed device surface, I believe. Nothing on the help page suggested that the fine details of the R read-only parameters will be as you

Hi, What's one way to convert an integer to a string with preceding 0's? such that '13' becomes '00000000013' to be put into a string I've tried formatC, but they removes all the zeros and replace it with blanks Thanks -- Regards, Anh Tran [[alternative HTML version deleted]]

Part 1) is basically that the initial rescaling is done if the window is too large to fit on the screen. That's true and obvious (no scrollbars) and intentional and on the help page. As ever, you need to report bugs on what is documented, not what you would like. This will be changed for 1.2.1, but was several hours' work. I have also cleaned up the scrollbar behaviour. Part 2) I just

Dear Community! I'm using the svm method of package e1071 for classifying my data. This really works fine, but however I have to work after creating the support vectors and the parameters with unscaled data. So the problem is when I try to train the classifier with the option "scale=F" the result is quite poor, so training with scaled data is essential. The rescaling of the support

Hi, I posted a few messages a couple of days ago about a strange windows 95 browsing problem with samba-2.0.2, 1.9.17p4 that none of our Windows 95 users can see our Linux shares, but all NT users can see the Linux shares, and all 95 and NT users can see AIX shares. All of our Linux and AIX use the save version of samba (I tested 2.0.2 and 1.9.17p4). Yesterday, I tried to down grade the version

I am using R version 2.12.1 on Win XP. I have done a heatmap with dendrogram using the heatmap.2 function. The heatmap basically looks like I want it to be, but the labels of the columns are cut off. I.e. the textual labels of the columns, although they are not very long (less than 12 characters), do not fit into the window and can not be read entirely. If I manually resize the graphics

Dear R-helpers, I don't see a difference between the following two plots of effect objects, which I understand should be different. What am I missing? require(doBy) require(effects) data(budworm) m1 <- glm(ndead/20 ~ sex + log(dose), data=budworm, weight=ntotal, family=binomial) m1.eff <- all.effects(m1) plot(m1.eff, rescale.axis = FALSE, selection = 2, main = 'rescale =

Apologies in advance if my comments don't help, in which case, no need to respond, but I noted in ?ksmooth: "bandwidth the bandwidth. The kernels are scaled so that their quartiles (viewed as probability densities) are at ? 0.25*bandwidth." So, could this be a source of the discrepancies you cited? Given that ?ksmooth explicitly says: "Note: This function was implemented for

Dear Sir, Madam, or to whom this may concern, my name is Jan Failenschmid and I am a Ph.D. student at Tilburg University. For my project I have been looking into different types of kernel regression estimators and corresponding R functions. While comparing different functions I noticed that stats::ksmooth returned different estimates for the same bandwidth as other kernel regression estimators
