read.table & readLines behaviour?
Hi, I have been using 'read.table' regularly to read tab-delimited text files with data. No problem, until now. Now I have a file that appeared to have read fine, and the data inside looks correct (structure etc), except I only had 15000+ rows out of the expected 24000. Using 'readLines' instead, and breaking up the data by tabs, gives me the expected result. I do not

how to display a string containing greek chrs and variables
I'm trying something that I thought would be pretty simple, but it's proving quite frustrating... I want to display, for instance, the correlation coefficient "rho" in a graph. I can do something like: text(x, y, paste("rho =", cor)) where cor would be my previously calculated correlation coefficient, and x and y the coordinates. Obviously that displays

Tinn-R editor question: saving syntax colour options.
Hi, after reading about it in the forum, I tried the Tinn-R editor (in WinXP) running R 2.5.0... nice one! However, I am trying to change the syntax-colouring from the default to my own preferences... and I can do that, but my options don't appear to be saved and get lost when I close Tinn-R. I've searched help menus, and google... and I can't find how to make sure my

Calling R from a Perl script: much slower?
Hello list, I use R for microarray analysis. One procedure I use takes a large matrix, and loops through it looking for specific rows, does an operation with them, and outputs a result (single row) as a row of another matrix. The loop goes on about 25000 times. When I run the loop directly from the R console itself, it takes about 3 minutes in my computer. I'm ok with that. Now,

negative number to positive number
Hello all, I know this is a pretty easy question but I can't find it in S poetry or R help. How can I make a negative number positive. Such as -5 to be +5 I tried +(-5), but that didn't work. So no, I don't mean taking a -5^2 just to get a positive number. This is in a function so it's not just -5 it's x. :) Thanks, Paul -- Research Technician Mass Spectrometry o The

Difficulty with formatting scatter.smooth output
Hello, I have been using scatter.smooth and been trying to format my plots and been unable to adjust the line type or color of the smooth curve. When I specify col in scatter.smooth, I can adjust the color of the scatter plot points, but the line always stays black and solid. lty has no effect. When I specify par prior to calling scatter.smooth, col will change the color of the points,

Legend outside plotting area
Hi, I have been trying many of the suggested options to place a legend outside plotting area, including something like this: par(xpd=T, oma=par()$oma+c(4.5,0,1.5,0),mar=par()$mar+c(1,0,1,0) But the aspect of the four plots gets compromised when I change the margin settings. I cannot use mtext because I need to use colors for the text. I tried layout, but wouldn't let me include

x axis problems
I have been searching for the R manual, unable to solve my problem. Questions 1) How can I put the x axis at the top of the plot? 2) I am plotting data from a CTD. I want to add series sal, obs and fluo at the same plot by using points(sal,deepth) ets. The data have different values so I want to use multiple x axis (4) with different scaling. How can I do that?

data.frame query
Hi All, Apologies for the simplicity of my question, but I would be grateful for any advice. Thanks I'm trying to put the output from a for loop into a data frame, however I have not been successful. The steps I have taken are: *R-code:* >for (k in 1:(nt-1-n0) ){ > n<- n0-1+k > lam=n/nt > Q=x[n] > output1<-data.frame(cbind(k,n,lam,Q)) > output1 > }

I intentionaly use informal terms, rather than technical terms whose exact meaning I might or might not know. I am finding this extremely frustrating. Every time I try to do anything,

selecting a group of points from a scatterplot?
Hi everyone, is there a way/package in R that would allow me to select a group of points from a scatterplot by drawing a circle around them or some such? I can use 'identify' to pick individual points, but that gets tedious if one has more than 10-20 spots. I can easily select spots within a rectangle defined by picking points using identify... but a simple rectangle sometimes will
