search for: vara

Hello,   I'd like to generate automatically all the possible combinations of a set of 8 variables (there are 535, too many to do it by hand). For example:   input: varA, varB, varC output: varA+varB+varC             varA+varB             varA+varC             varB+varC             varA             varB             varC Is there any function that produces this option?   Thank you [[alternative HTML version deleted]]

Hello, I have a dataframe of say 20 lines with one line per individual. I want to group these 20 individuals by length class (eg. of 5cm) and get the mean value of all the other variables (eg VarA and VarB) for each length class My dataframe is as follow: Length <- 10:30 VarA <- seq(1000,1200,10) VarB <- seq(500,700,10) Data <- cbind(Length,VarA,VarB) And I want to get something like: Length Class Mean VarA Mean VarB [10-15[ 1020 520...

Dear R Users, Am using lm() with contrasts as below. If I skip the contrasts() statement, I get the coefficient names to be > names(results$coef) [1] "(Intercept)" "VarAcat" "VarArat" "VarB" which are much more meaningful than ones based on integers. Can anyone tell me how to get R to keep the coefficient names based on the factor levels whilst using contrasts rather than labelling them with integers? Many thanks in advance,...

Hi, I'm pretty new to R and I've been having some problems filtering data in matrices. I have the following initial dataset: || year | name | varA || I have multiple values for "varA" for the same "year" and the same "name". Having this as the input I would like to obtain the following: || year | name | {varA mean} || Where I only have one line for each "year" and "name" with the mean of th...

Let's say I have a program that returns variables whose names may be any string within the vector NAMES=c("varA","varB","varC","varD","varE","varF"..."varZ"), but I do not ever know which ones have actually been created. So in one example output, "varA", "varC", and "varD" could exist, but in another example out...

Hi, I wonder whether the following is possible with R, and whether anyone has done that and can share his/her code with me. I have a correlation matrix, and I want to create a correlation table that I can copy to Microsoft Word with a superscript above each correlation, indicating significant differences in the same row. That is, when correlations in the same row do not share superscript, it means

...n the two graphs printed pair by pair is fairly large. Can I remove/reduce the area that seems reserved for Title and X label so that, on a page, the space between the graph at the top and the one at the bottom is minimized? 3. Given the function below, I haven't discovered a way to have "vara" appear as the Title or Y label in graphs. main=as.character(vara) lists all the values of vara (which is a column from the data frame d). So, how can I use the name of a vector as title or label in a plot? Thank you, b. d <- ('data.csv', header = T, sep = ",", quote=&q...

Dear list members, Where can I find code for computing the p*p variance-covariance matrix given a vector of p variances (ordered varA, varB, ..., varp) and a vector of all possible correlations (ordered corAB, corAC, ..., corp-1,p)? I know that the covariance between 2 variables is equal to the product of their correlation and their standard deviations: corAB * varA^.5 * varB^.5 and so: covAB <- function(corAB, varA, varB...

...everyone, I'm doing some coxph() analyses with a large and complex dataset. The data was collected in different centers, so I am using strata(centers) to stratify the analysis. My main issue is, not all centers collected all the variables, so for a model such as: coxph(Surv(days, cancer) ~ varA + sex + strata(centers), data) I might have 1 or more centers that have NA for varA (in practice, all the individuals monitored at those centers come without varA). coxph() obviously warns me that a number of individuals have been excluded -- would that be equivalent to doing the analysis on a su...

In stead of writting the 9 lme models, I want to do it sistematically (the example is a simplification of what I really have). Here you have the comands for the first model: library(nlme)...
