I've had a question a few moments ago about how to create multiple objects from multiple files within a loop. Thanks for the quick answers, it worked with "assign", like this: for(i in seq(1,nfn,1)){ fin<-paste("/home/klimet/patrick/LAEGEREN/NEBEL/FOGEVENT2000/",fn[i],sep="") assign(paste("f", i, sep = ""),

Dear R-users, I'm trying to extract the exact location of the maximum value in a vector or a matrix, meaning I want not only the maximum itself but also at which position (e.g row 6, column 12) it is located. I appreciate any suggestions. Thanks, Patrick -------------- next part -------------- A non-text attachment was scrubbed... Name: patrick.vcf Type: text/x-vcard Size: 339 bytes Desc:

Dear colleagues, I often use chemical formulas to label my x-axis, e.g. in barplots. I used to do this like the following example and it worked just fine: a <- seq(2,24,2) b <- seq(3,36,3) c <- rbind(a,b) barplot(c, width=c(0.9, 1.1),space=c(0.2, 0.75), col=c("indianred4", "yellow2"), beside = TRUE, xlab="Ions", yaxt="n", xaxt="n", ylab

Dear R Community, When making a summary with a vector, the result is "numeric" and I can recall its components (like median, mean, etc.) for further use. However, if I use summary with a matrix, the result is of mode "character" (like "Median : 1.2127") and I cannot extract the results for direct further use. Thanks for any hints, Patrick -------------- next part

Hi there, I'm a new R user and I've got a little problem: I would like to read several files at once (which works) and create R objects for each individual file (which doesen't work) within a loop: this is the way I've tried to program this: fn<-list.files(path = "/home/klimet/patrick/LAEGEREN/NEBEL/FOGEVENT2000/", pattern=NULL, all.files=FALSE, full.names=FALSE)

Dear Martin Pool. We regularly use rsync for making backups of our file systems but we have noticed that the atimes are not transferred with the files and are also always updated on the sender's side. Therefore, we have created a modified version of rsync based on rsync-2.6.6 protocol version 29 which transfers the access times with the transferred files and also allows to preserve the access

Easy question that I can't find an answer for. I'm trying to subset a data frame and want to exclude the positive values, i.e. I want the NA values. My data: > summary(temp$tuna) Min. 1st Qu. Median Mean 3rd Qu. Max. NA's 1 2 3 3 4 5 1211 Querying for subset(temp, tuna %in% "NA", select.... subset(temp, tuna == NA,

I understand that NA's in character vectors are displayed differently than NA's in factor vectors. > c("x", NA, "y") [1] "x" NA "y" > as.factor(c("x", NA, "y")) [1] x <NA> y Levels: x y That seems sensible enough. But shouldn't I see the same behavior in a dataframe? > test <- data.frame(a =

Dear all, I installed the amd64 cran2deb [1] JGR binaries on a fresh Debian testing, and JGR is missbehaving. When JGR starts up, one core of the CPU goes to 100% and stays there, even though I am keeping it idle and not performing any operation. I tried JGR with both sun-java6-jdk and openjdk-6-jdk, debian-liv:/home/liviu# update-alternatives --config java There are 4 choices for the alternative

Hello! I have a dataset with NA's in some variables (factors), for example: $ P67 : Factor w/ 2 levels "-","+": NA 2 1 NA NA 2 1 1 2 NA ... I need to use 'xtabs' like xtabs(~x$P67) It works well and produces something like this: x$P67 - + 779 1318 but i want to compute NA's too, like this: x$P67 - + NA 779 1318 137 I am trying

Hello, I am trying to analyze sociological survey data using R. It is often important in survey to calculate both the actual factor sums and percentages (easily done with describe() ), but also the numbers and total percentage of NA's. Often it is important to present NA's in graphs besides the factors. Is there any easy way to make R treat NA's as if those were factors besides other

Hi, this following code: x<-c(1,2,NA) length(x) returns 3, correctly counting numbers as well as NA's. How can I exclude NA's from this count? Ralf

I wonder if anyone could help me find an expression for skipping the last missing values in a vector? The kind of material I have is something like x<-c(23,12,NA,23,24,21,NA,NA,NA) I would like to skip the last NA's, but not the ones in between other vallues. Any hints? (Why not do this by simply take x[1:6]? I have several vectors a couple of thousand observations long with varying

Hi, To obtain estimates for some missing values in my data I fitted a linear regression and then used the command fitted(model) to get the fitted values from the model, but R doesn't return any values for the NA's. I can calculate the fitted values from the estimates obtained from the summary of model, but that's not very handy. Is there a way to include the missing values in the

Consider > summary(1:5) Min. 1st Qu. Median Mean 3rd Qu. Max. 1 2 3 3 4 5 > summary(c(1:5,NA)) Min. 1st Qu. Median Mean 3rd Qu. Max. NA's 1 2 3 3 4 5 1 Wouldn't it be more stringent if "NA's" was also reported in the first case?? Regards S?ren

Dear R colleagues, I am trying to create a new column in a data frame, which converts values and NA's from another column into binary format. Essentially I need the NA's to become 1 and the rest to be 0. The code I wrote is returning the following error message: Error in if (mort[i, 4] != NA) mort[i, 8] <- 0 else if (mort[i, 4] == : missing value where TRUE/FALSE needed

Hi, I'm trying to do a filled.contour plot where some points are labelled as NA. How do I could plot this kind of graphics, so NA points are coloured black, keeping the levels of remaining points. NA's values represent land points (meaningless), and what I want to plot is the levels of a variable over the sea. x<-seq(length=21, from=-10, by=.25) y<-seq(length=8, from=36,

I noticed some odd behavior when I transpose a data frame containing NA's. It seems to cast all the elements as "character" including the NA's. Bug? > t(data.frame(x=1:10,y=1:10,z=rep(NA,10))) 1 2 3 4 5 6 7 8 9 10 x " 1" " 2" " 3" " 4" " 5" " 6"

Hi all, I have a data set with missing value. I would like to estimate those missing value by using normal ratio method. Below is part of my data: AS BL Serdang Jhr Phg Target station 0 0.0 12.8 0.0 23.7 0.0 6 0.0 81.7 0.2 0.0 NA 0 1.5 60.9 0.0 0.0 15.5 1 13.0 56.8 17.5 32.8 6.4 4 3.0 66.4
