Hi Folks, I am dealing with data which have been presented as at each x_i, mean m_i of the y-values at x_i, sd s_i of the y-values at x_i number n_i of the y-values at x_i and I want to linearly regress y on x. There does not seem to be an option to 'lm' which can deal with such data directly, though the regression problem could be algebraically

I am using an example posted in this help forum to work with a file. the head of the file looks like: 988887 2007-03-05 2007-06-01 90 3 5.450 205500.00 999.00 999.000 0.000 0 0 988887 2007-03-06 2007-06-01 90 3 5.450 205500.00 999.00 999.000 0.000 1 0 988887 2007-03-07 2007-06-01 90 3 5.450 205500.00 999.00 999.000 -0.100 2 0 988887 2007-03-08 2007-06-01 90 3 5.450 205500.00 999.00 999.000 -0.100

I am dealing with a huge matrix in R (20 columns, 54000 rows) and have lots of missing values within the dataset which are currently displayed as the value "-999.00" I am trying to create a new matrix (or change the existing one) to display these values as "NA" so that I can then perform the necessary analysis on the columns within the matrix. The matrix name is temp and the

Hi. I encountered a following problem, if I state for example: package{"aspell-en": ensure => absent, } package{"aspell": ensure => absent, } I get error in logs because of dependencies. It seems that puppet uses ''yum'' for installation on CentOS and ''rpm -e'' for removal of packages, so it cannot handle this kind of dependencies:

I have some data set which has some values -999.000 & I would like to remove whole row of this kind of values. e.g a<-matrix(c(1,2,3,4,4,5,6,6,-999.99,5,9,-999.00),nrow=4) a<- [,1] [,2] [,3] [1,] 1 4 -999.99 [2,] 2 5 5.00 [3,] 3 6 9.00 [4,] 4 6 -999.00 expected answer [,1] [,2] [,3] [1,] 2 5 5.00 [2,] 3 6 9.00 I

``We all know'' that R has more flexible and nicer color specifications than S-plus. There are situations however, where I'd like to specify colors numerically, e.g. 1) convenience of using different colors in a for(.) loop or 2) backward compatibility with S. In S, there's the quite known ``standard'' col = 0 :<==> current background color [ = white by

Hi. I have a correlation matrix 'x' which is of size 923x923 I need to remove variables that are highly correlated. I don't have a sophisticated way of selecting which of the two in a highly correlated pair to remove. I thought I would just go through each entry of the correlation matrix and if it is greater than 0.6 (or less than -0.6) I will remove that column and then redo the

Dear useRs, I have a longitudinal experiment with several treatment groups, ~20 subjects per group, ~6 timepoints and a continuous dependent variable. I have been successfully been using lattice::xyplot with this data. However, I have been stumped with a particular application of it. I would like to use xyplot on my data, broken into treatment groups with the groups argument, using

Hello R Help List, I am an R novice and trying to use the ifelse function to create a new binary variable based off of the responses of two other binary variables; NAs are involved. I pulled it off almost successfully, but when I checked the counts of my new variable for accuracy, I found that a small portion of the NA cases were not being passed through as NAs, but as "0" counts in my

useR's, I need help getting a Fortran DLL successfully returning the correct output. The attached fortran source code (filter2d.f) and DLL (filter2d.dll) are attached.

Hi All I am looking for a way to prefix a constant value to all the rows in column in a data frame. Eg. V1 2 3 4 5 I want to make it like this V1 number2 number3 number4 number5 Thanks! -Abhi [[alternative HTML version deleted]]

Hello Gurus, I am still new to R. Here is my issue. I was trying to add column to data frame that was populated by read.spss(). When I used cbind to add a new variable(column). library(foreign) mydf<-read.spss(file="C:/myspss.sav",use.value.labels=FALSE, to.data.frame=TRUE,use.missings=FALSE) attr(mydf,"variable.labels") ## it gives you all the labels

Dear R-helpers, x <- rep(1:2, 4) y <- c(2, 4, 3, 5, 1, 3, 2, 4) w <- factor(rep(1:2, each = 4)) v <- rep(1:2, each = 2, 2) xyplot(y ~ x | w, groups = v, type = 'b') How do I tell xyplot to use four colors and four plot characters and four line types? And how do I set up an appropriate key in each? _____________________________ Professor Michael Kubovy University of Virginia

Hi guys. The 'col'-parameter in the 'hist'-method for the classes 'POSIXt' and 'date' does not perform as it does in the default 'hist'-method. Unfortunately, it does not only change the filling color of the boxes, but also the color of the axislines. [Using 'graphics'-package version 2.2.0] Examples: # with POSIXct-object hist(.leap.seconds,

I have a very short question. Is there any possibility to give to the parameter "col.axis" of graphics function "axis" a vector value of many colors instead of just one color, otherwise is there any way around it? Thank you very much Enio Jelihovschi UESC - Brazil [[alternative HTML version deleted]]

Hi, I am trying to color the data points on my boxplot but I only get the default black. Not sure why. Any ideas? Thank you, Mark Here is my code. > dat.g100 <- dat.sg[100,] # selected gene (row) from a dataframe of 37 columns > d1 <- as.matrix(dat.g100[,1:18]) # subset 1 > d2 <- as.matrix(dat.g100[,19:37]) # subset 2 # boxplots > par(mfrow=c(2,1)) > boxplot(d1,

Hi list, My data set is comprised of 47 columns and about 700 rows. Most of the values would be around 2, while some will go beyond in either direction, higher or lower. Is there a way to specify the parameter of col or others if necessary to have the range of representing colors be 0----8, and make dark for 2, red for higher than 2 and green for lower than 2. Is there a way to do this? Thanks a
