Hey all, I learned that using the equals sign "=" to assign objects is generally OK, but will not work in some cases. As I always use "<-" for assignments, I have not encoutered any problems. Could somebody provide an example or explanation, why getting used to "=" is not a good idea? Or is it? Thanks ahead, Berry ------------------------------------- Berry

Hello dear developers, I find myself often having the result of "range" oder "extendrange", which I want to create a sequence with. But "seq" needs two seperate arguments "from" and "two". Could an argument "range" be added? Otherwise I will have to create an object with the range (may come from a longer calculation), index twice from

hi, say I have consecutively numbered objects obj1, obj2, ... in my R workspace. I want to acces one of them inside a function, with the number given as an argument. Where can I find help on how to do that? Somebody must have been trying to do this before... Some keywords to start a search are appreciated as well. Here's an example, I hope it clarifies what I'm trying to do: obj1 <-

Hey again, I didn't wat questions to get mangled up, so here's my second email. In matlab, there is the simple possibility to access colums x till last of a matrix using mydata(1:3, 5:end). In R, I so far use mydata[1:3, 5:ncol(mydata)] Is there a faster way? (in terms of typing) Thanks ahead, Berry ------------------------------------- Berry Boessenkool University of Potsdam,

Hi all, I'm working on a function that reads online data that is only available to certain IPs. It then writes a subset of the data into a file. So whenever I'm logged in elsewhere or am not connected to the internet, I get an error, and the function is terminated. I want it to rather print a message into the file. Is there any way to test whether a connection can be opened? Analogous to

Hey all, I encountered a problem drawing a histogram. You can view the picture here: http://dl.dropbox.com/u/4836866/Bad_Histogramm.png What happens: the bars are drawn with different starting points, thus no straight zero-line is there. And bars are overlapping. (or sometimes apart from each other.) How it happens: hist(volcano, breaks=10) # and any other data This also happens with

Hi everyone, I'm trying to print a table justified to the left, but it doesn't work. Any hints? KennArt <- data.frame(NR=c(171,172,174,175,176,177,181,411,980), TYP=c("K?rnermais", ?"Corn Cob Mix", "Zuckermais", "Mischanbau (Silo)Mais/Sonnenblumen", ?"Mais mit Bejagungsschneise in gutem landwirtschaftlichen und ?kologischen Zustand",

Hi, I'm curious about Tab stops in graphics: plot(1) text(1.2, 1.2, "Char\nMoreChar") works fine, but text(1.2, 0.8, "Char\tMoreChar") doesn't. Exporting with pdf tells me that the sign width is unknown. I'm not into informatics, so I don't know how a tabstop actually works. Is this at all possible in graphical commands as it is in write.table and the like?

Does anybody know how to get a pdf file with landscape orientation?. pdf(file= 'my_file.pdf' ,onefile=T,paper='A4') plot(sin, -pi, 2*pi) dev.off() Thank's in advance Juan A. Hernandez Spain [[alternative HTML version deleted]]

Hello, I wonder if someone can elaborate on why in the first graph I am able to set labels vertical to the x-axis but not in the second. I tried to select the window but it didnt really help. Many Thanks Paolo ExtAvgCWV = rnorm(200) ExtAvgDemand = rnorm(200) ExtGasDays = seq(from = as.Date("2010-8-4", "%Y-%m-%d"), along.with = ExtAvgCWV, by = "days")

Hi all, I want to label an axis with exponents, but can't get it done with expression. Any hints would be very welcome! # simulated data, somewhat similarly distributed to my real data: set.seed(12); d <- rbeta(1e6, 0.2,2)*150 ; d <- d[d>1e-8] hist( d? , breaks=100) # now on a logarithmically scaled axis: hist(log10(d), breaks=100, xaxt="n") abline(v=

Hi, I'm writing a function that needs the input names (as characterstrings) as part of the output. With deparse(substitute( ) ) that works fine, until I replace all zeros with 0.001 (log is calculated at some time): tf <- function(input) { input[input==0] <- 0.001 ; deparse(substitute(input)) } myguess <- 42 tf(myguess) # not "myguess", but "42" Now when

All - When I plot something like a<-rnorm(5) b<-rnorm(5) plot(a,b,col = "red") points(10,-10) The last point is missing because it is out of range of the first plot. I just try to switch from Matlab to R. In Matlab, it always can automatic adjust the xlim and ylim for such case. Is it possible auto adjust in R? Otherwise keep tracking xlim and ylim is really annoying.

Hey all, I was wondering about the order of execution of functions and found that, in fact, I should look at the topic of buffering output to the console. Which I did - below are some links of related topics, in case anyone wants to read up on it. I decided to change the concerning lines in the file "Rconsole" in the "etc"-folder to ?? ## Default setting for console

I have a suggestion about the heartbeat and the way that "downed node" detection works. There are occasions where a node is up, and for whatever reason, I need to power cycle it (for instance, a frozen process, etc). In these instances, my other nodes are unable to perform file system operations until the heartbeat period expires. This ends up being somewhere around 30-60 seconds (this

Hello, I am using the function simple.violinplot from the package UsingR. I have some outliers in my dataset so that the distribution has very long tails. As a result, the y-axis of the output of simple.violinplot extends to very large values. I would like to zoom on the y-axis with a command such as ylim=c(a,b), as in boxplot(x,ylim=c(a,b)). However, doing simple.violinplot(x,ylim=c(a,b)) does

Hi all, I improved a function drawing horizontal histograms (code below) which uses barplot and works fine. It does,however, need to assign a function to the global environment to later find the actual location on the vertical axis, and not the number of bars used by barplot. Hopefully, running the examples below will illustrate that. As said, it works perfectly fine and does exactly what I

Dear R-experts! Running a meta-analysis (using the magnificent metafor-package), I use cohen's d as a main outcome measure in a random-effects model. For most of the samples cohen's d is derived form a comparison of two groups (A & B). However some studies report results from an ANOVA (one-factor with three levels: C,D,E) whereas two groups (C,D) correspond to one group in the other

Some thoughts for the new year: 1) MDCT is good for image coding 2) image coding and audio coding are two very different things 3) combine 1 and 2 4) if a psycho model is good, after leaving out what it tells you you can without hurting quality, applying the same model should yield the same results as you got before 5) from 4: decode -> encode -> decode should result in (almost) the
