Hi all, probably really simple to solve, but having no background in programming I haven't been able to figure this out: I have two dataframes like df1 <- data.frame(names1=c('aa','ab', 'ac', 'ad'), var1=c(1,5,7,12)) df2 <- data.frame(names2=c('aa', 'ab', 'ac', 'ad', 'ae'), var2=c(3,6,9,12,15)) Now I want merge

Hi R users, This seems like a simple problem but I have searched nabble for the answer and can't seem to find it. All I want to do is produce a boxplot where I have two boxes for one Individual but on the xaxis I only have one tick mark centred between the boxes so I can add the Individuals' name.

Hi R users: I got this code to generate a graphic for each member of a lists. list1<-list(A=data.frame(x=c(1,2),y=c(5,6)),B=data.frame(x=c(8,9),y=c(12,6))) names1<-names(list1) sapply(1:length(list1),function(i) with(list1[[i]],plot(x,y,type="l",main=paste("Graphic of",names1[i])))) Is there a more elegant solution for not to use two separate lists? I would like to

Hello R Gurus, I have a matrix for which I am doing a heatmap using heatmap.2. I want to put the rownames on the lefthand side instead of the right side of the heatmap. how can i put the rownames on left hand side: I have already tried axis but could not make it work ccc<-structure(c(1, 0.283300333755851, 0.237863231117007, 0.0148696794159253, -0.0780756406815149, -0.106161465097659,

Hi there, I have been using the example provided bellow for a while, and It was working without any problem. Nevertheless, just since 2-3 days is not working, probably because I did update.packages(). I have tried to re-install the older versions of the packages Hmisc() and xtable(), but still does not work. Can you run this example, and tell me if you got the same problems? I use

Hi all, I want to execute a loop of a program: for (u in Timeframemin:Timeframe){} Imagine that Timeframemin<-10 Timefram<-10000 Is it posible to execute the loop but only proving from 10 to 10000 but jumping 10 each time, for example, execute for 10,20,30.....to Timeframe. Other question is, when a program is "heavy" and has a lot of loops to execute (how can I know where

useR's, I want to apply this function to the columns of a data frame: u[u >= range(v)[1] & u <= range(v)[2]] where u is the n column data frame under consideration and v is a data frame of values with the same number of columns as u. For example, v1 <- c(1,2,3) v2 <- c(3,4,5) v3 <- c(2,3,4) v <- as.data.frame(cbind(v1,v2,v3)) uk1 <- seq(min(v1) - .5, max(v1) + .5,

Hi, I am so novice in using R. I have some problems in my R script below which fits time series data and predict it one-step ahead. Here is a brief explanation on what I try to achieve Th16k is time series data (500 data points). The size of window for fitting and predicting is 50 (data points). As you can easily discover from my code, (fixed) window is moving/sliding to get next one-step

Hi, I' ve read in several files with measurements into R data frames(works flawlessly). Each dataframe is named by the location of measurement and contains hundreds of rows and about 50 columns like this dataframe1. date measurment_1 .... mesurement_n 1 2 3 .. .. .. n For further processing I need to check whether or not ncol and colnames are the same for all dataframes. Also I need to

I am having some trouble getting the colors correct on county maps using the maps package. I have a data.frame that contains coloration data for every county -- it also contains a variable 'mapm' which fits the 'state,county' format used in the mapping package. I use this to define colors from a range of 1:100. The problem is that the colors seem good for some states/counties,

On a typical embedded Linux device, with no MMU, there is no fork() or it returns ENOSYS. The nearest replacements are vfork() (which is only useful before exec*()), or to create threads with pthread_create(). rsync would be a very useful program on such devices, and I was a bit disappointed to build it, only to find the compile went fine but it failed at runtime due to ENOSYS. Is there any
