Dear all, I am interested in reading Excel spreadsheets (*.xls) directly into R (I am using version 1.1.1 at the moment). I have not had much luck so far. For the time being, I have been converting Excel files to comma delimited files (*.csv) and reading these into R (using commands such as "read.csv"). This works well, but it would be more efficient if I could read the Excel files

I am using the "chron" package. Can anyone tell me if there is a simple way to convert a date object (obtained from the "dates" function) into a julian date (using the "julian" function)? Thanks, Al.

Hi, all I wanted to fetch data from Bloomberg for govt bonds, and analyse it further. I am having trouble in getting data as when I use field=PX_LAST, it is giving the prices but when I use field=CPN, or ISSUE_DT, it is not giving the results and just bouncing back <NA> for that. This is the piece of code: > library(rJava) Warning message: package 'rJava' was built

I have 3 packages on CRAN that I developed with my govt email address. I'll be retiring in a month and that email address will no longer work at some point. I realize that I need to change the maintainer address and I've already done that with one package but my question is do I need to remove all references to my govt email address listed as author in various files and replace with my

I've had a play with this and, due to my own short-comings, remain none the wiser. In particular, I'm not sure what value of 'spar' is consistent with the magic lambda=1/1600 for quarterly data. I initially interpreted spar as lambda and tried setting spar=1/1600. This results in almost no smoothing while spar=1600 causes an error. The smooth.spline function seems to want

Hi all I would like to perform a logistic regression analysis on some complex survey data with R, but am not sure if there are functions within R that will enable me to do so. Also, are there any extensions of the "cor" function that would enable me to incorporate survey weights when calculating correlation coefficients for bivariate data. Any help on this matter will be greatly

Well, you don't give much of an example.... I'm replying CC to the R mailing list. Please ask questions there, rather than adressing individuals for basic help. Here is one; does it answer your question ? data(agriculture) ag.ag <- agnes(agriculture) class(ag.ag) pltree(ag.ag) # the dendrogram, if you want to see it ## cut the dendrogram -> get cluster assignments: (ck3 <-

Hi all Apologies for any cross posting. I have encountered a rather bizarre "problem" in Splus and R. I am using Age-Period-Cohort models to model cervical cancer and have run the same data on both R (v.1.4.1 & v1.6.2) and Splus (version 6.0). I used the same command line in both Splus and R: glm(cases~-1+as.factor(age)

Respected all, I am working on a socio-economic survey (named as National Sample Survey in India provided by National Sample Survey Organization, Govt. of India) data of individual as well as households.

Hello, I am a (relatively) experienced programmer, but new to R. I have a problem using R 1.9.1. I have fit some data using glm(), from within a function: formula = as.formula(paste(depvarname, "~", rhs), env=globalenv()) return (glm(formula, family=binomial(link=logit))) I have now come back to the formula and want to add some more variables to it. So I do:

Hi all I hope you might help me with some aspects of producing a graph in lattice. There are three things I have struggling with and that is: 1. to separate the horizontal box rows from each other; 2. to change the colour of the horizontal and vertical strips to white; and 3. to place the axes labels on the left y axes and on the bottom x axes. I would really appreciate some help. I have put the
