Hi: I have made a lot of progress reading and manipulating large data files, thanks to the help of several of you. I am now stuck with writing the final file with the following error (see also the full transcript below): Error in as.matrix.data.frame(x) : length of dimnames[2] not equal to array extent I do not know what it means and could not find how to get around that in the manual nor

The example scene: I have a database with stats about each goal made by my soccer team. This database (a data frame in R) is organized in lines (goals) with a set of columns containing data about these goals (player name, tactic position, etc). For now, this database will be called "data.frame1". What I need is to feed this "data.frame1" with new information about my team

hello list, Can someone help me figure out why the following code doesn't work? I'm trying to but both Greek letters and subscripts into a tcltk menu. The code creates all the mu's, and the 1 and 2 subscripts, but it won't create the 0. Is there a certain set of characters that R won't recognize the unicode for? Or am I input the \u2080 incorrectly? library(tcltk) m

Dear all, I have data like 3 coulmns and many rows. Each entry is less than 10. Example x y z 1 5 3 2 2 3 7 8 3 8 9 5 4 5 4 6 -------------------------- --------------------------- I have to sum entries of each coulmn (seperately) till it be 10. This i have to start for each row. And I want to assign no. of rows needed including that row too(it to be 10 or 10+, the moment it exceeds 10, i

Hi, I am an R newbie and one thing I am having trouble with binding variables that I have created within one data frame into a new data frame when using na.omit(). To illustrate this problem I will give the example I am working on and the approah I have been using:- data.frame1<-filepath.... attach(data.frame1) #create a new variable using a function new.variable<-rep(1,length(weight3))

Hi, I am using RInside for one of the applications that I'm using. The error that occured is as follows. When I use R.parseEval("xyz") if the parse fails then the mb_m is not cleared and hence all subsequent calls to R.parseEval fail. example: when R.parseEval("stringConcatfactoryrandom") is executed the R instance looks like this (gdb) p R $7 = (RInside &)

Hi all, I have 20 data frames, named frame1, ... , frame20. Each data frame has the dimension 20x5. I need to build a function that calls out the observation in Row 1, Col 2 from all 20 data frames and places it in a vector of length 20. I have tried the following code: vect <- rep(0,20) for(i in 1:20){ vect[i] <- paste("frame",i,"[1,2]",sep="") } The

I have a dataframe D.F1 >dim (D.F1) 14351 9 This dataframe has values and for some 1000 rows it holds NULL values.I hace found the missing values for about 500 and have those in another dataframe D.F.sub.2 >dim(D.F.sub.2) 500 9 as dataframe is a subset of D.F1 the coulmn 1 in D.F.sub.2 is a subset of D.F1.I have to insert the values in D.F1 in other fields while the coulmn 1 in both

Hi, I'm looking to combine two data frames. Several of the columns are in common while the others need to be summed up. The apply functions and the merge functions don't seem to be working. I've included a basic example of what I'm trying to do below. Thanks! Sean data.frame1<-as.data.frame(matrix(c('winter','dredge','515',100,150),1,5))

Hello R friends, I get quite confused in using the grid graphic function grid.pack( ) and grid.frame ( ). Here is a simple example: library(grid) grid.frame(name="frame1") grid.pack("frame1",rectGrob(width=unit(0.5,"npc"), height=unit(0.5,"npc"), gp=gpar(col="red"))) what I expect is a rectangle with half the default device's

This is a follow-up to bug sent to days ago, which bounced from r-devel because the example was to large. Now example is smaller, and behaviour is as belo, EXEPT that r-windows not any more bombs, so main problem is "xpdrows.data.frame"??? By the way, how to debug this example under windows? debug() doesnt accept the functions used (.Primitive), and R wont run under gdb --- may have

I am positive this problem has a very simple solution, but I have been unable to find it, so I am asking for your help. I need to know how to look something up in one data frame and add it as a column in another. If I have a data frame that looks like this: > frame1 ID score test age 1 Guy1 10 1 20 2 Guy1 13 2 20 3 Guy2 9 1 33 4 Guy2 11 2 33 and another frame that looks like this:

Hi, I have a data matrix with 13 columns and 55 rows. First coulmn is year and other are monthly values for 55 years. Now i want to create a single column of all the values ( i e a single time series column from column 2 to 13 ). Is it the for loop that works here ...how ? or how i can rearrange the data so that it becomes a times series column. hope i made the question clear . thank you,

Hello, i want to match a column of one data.frame to another, my problem is, that i only want to match the data, if 2 columns are equal. i have a example: data.frame1 cu.nr. name value A 1 Evo 100 B 1 Mer 80 C 2 Ford

Hi, What is the difference between the R installation from source and the R installation from ubuntu repositories. Specifically when I install R-3.1.1 on ubuntu 14.04 from sources ldflags and CXXFLAGS are different that those from the installation from a repo. Installation from sources: R CMD config --ldflags -Wl,--export-dynamic -fopenmp -L/home/prana/prana_R/third-party/install/lib/R/lib

I'm trying to do a linear discriminant analysis on a dataset of three classes ("Affinities"), using the MASS library: > data.frame2 <- na.omit(data.frame1) > > data.ld = lda(AFFINITY ~ ., data.frame2, prior = c(1,1,1)/3) Error in var(x - group.means[g, ]) : missing observations in cov/cor What does this error message mean and how can I get rid of it? Thanks! Pieter

Hello all, I am trying to use "clim.pact" package for my work, but since this is the beginning for me to use gridded datasets in "R", I am having some trouble. I want to do seasonal analyses like trends, anomalies, variograms, EOF and probably kriging too to downscale my 1 degree gridded data to 0.5.  So, as a first step, I compiled my entire dataset (with 25

Hello. I'd like to produce a simple pairs-like plot with two data frames - but not a traditional scatter-plot matrix - just multiple bivariate plots of data.frame1[i] vs data.frame2[i] ... In other words, given data frames X and Y, I'd like multiple plots on a page like: Y1 Y2 Y3 X1 X2 X3 Thanks in advance. -R
