Hello, I would like to know if there is a simple way of adding labels to the points in a pairs() plot. I am thinking of something like using the text() function when adding labels to a regular plot. Thanks...

Hello, Is there an option I can easily set to put labels next to the points in a simple plot? The closest I got to it was to use the option pch, but this replaces the point symbol with the...

Hello, Is there an easy way to remove a few columns from a data frame by indicating the column names? I am thinking of an operator like the "-" to remove the columns when referenced by column number, and I don...

In case you have access to Excel, you can open the file and save it in Comma Separated Values format and then read it into R using read.csv. At 05:23 PM 16/7/2002 +0200, jimmy melinard wrote...

Hello, I would like to know how to test whether the 'subject' random effect is significant in a generalized linear model. I am using glmmPQL() in the MASS package. The response is binary and my model only has an intercept...

Define the variable as a factor. Suppose you have a response 'y' and a regressor 'x' that has the binary variables, then do: lm(y ~ as.factor(x)); This is also valid for any categorical variable, not only for binary...

Hello, I would like to know if it is possible to add new points to a given plot and that the axis ranges be automatically adjusted so that all the new points are seen in the plot. For example, I...

Hello, I have a data frame whose columns are factors with numeric levels and I want to convert the columns to numeric so that I can treat the data frame as a matrix. I found a way of doing this...

Hello, I have fitted a multivariate linear model using lm() but then I cannot apply any function available for diagnostics, such as lm.influence(), rstudent() etc. I get the following error message when calling any of the above functions. "Error...

Hello, I had the following problem occurring too often lately: R hangs up unexpectedly. It usually happens when I am switching windows within R or when I am going back to the R window from another program. At first I...

Hello, I use the option xaxp in the plot function and it is not recognized. This affects the result of the function grid(), since it takes the default tick marks used by the plot function, which is not what I...

Hello, I have the following two questions, rergarding: (Output) 1) Is it possible to have the output of a command automatically displayed, without explicitly requesting it after the command, and without using the print() function? For example, I want to...

Hello, I have the following situation: Suppose I have the string "test(x)", and I want to substitute x by y. I know that this can be done by using the following commands: string <- parse( text="test(x)" )[[1]]; do...

You could find the number of digits by doing a while loop: ndigits <- function(x) { n <- 0; rounding <- 1; while (rounding > 0) { rounding <- floor(abs(x)/10^n) * 10^n; n <- n + 1; } return(n-1) } Daniel Mastropietro At 09...

Hello, I would like to know if this behaviour in R is as expected. I have a data frame 'dat' with column var1 being character (and not factor). Then I create a new column 'var2' by: > dat[,"var2"] <- dat$var1...

There are the functions mdy.date() and as.date() in the survival library, that convert to Julian date. At 02:33 PM 23/7/2002 -0300, marcelo wrote: >Dear R-users > >I have some doubts about with converting dates... >e...
