Dear all, I am a new user of R. I would like to know how to get fund's returns in percentage (%). For example, I use: R <- ts(read.xls("FundData"), frequency = 12, start = c(1996, 1)) Whith this program, the returns are like 0.0152699. But, I would like to have 1.52%. Please advise me about the function. Thanks! Fabrice

Hello fellow R's, I'm sure there must be an easy way to do this. But after digging in the documentation and thinking about it for a while I couldn't figure it out. I need to get a decreasing recursive vector in. I mean something like this: if starting at 2, and ending at 6, the vector should be 2 3 4 5 6 3 4 5 6 4 5 6 5 6 6 An easy way would be to do this x <-

Hi, I just installed jEdit but have no clue, whether I can run my code a'la "ctrl-R" directly from jEdit script, or should source it from R command line, after saving it first in jEdit. thanks for any help, rob -- View this message in context: http://www.nabble.com/jEdit-for-R-tf4684065.html#a13384782 Sent from the R help mailing list archive at Nabble.com.

Hello list, I read in a txt file using <B<-read.table(file="data.snp",header=TRUE,row.names=NULL) by specifying the row.names=NULL so that the rows are numbered.

Hello fellow R's, I apologize if this question was answer elsewhere. I have an executable file that I need to run from R. Basically I want to use R to create the input files this executable requires, then run it, and finally use R again to analyze the output files. Because I have to do this many times I'd like to have the R code call the executable file after the input files are

Dear list, I'm interested in fitting a generalized additive model in which some of the covariates are derived quantities and known measurement errors, and I am not sure how to incorporate the uncertainty of these covariates into the model fitting process. Could anyone point me towards relevant examples or documentation? Thanks in advance, Julian Julian M. Burgos Fisheries Acoustics

Dear list, I do apologize if these are basic questions. I am fitting some GAM models using the mgcv package and following the model selection criteria proposed by Wood and Augustin (2002, Ecol. Model. 157, p. 157-177). One criterion to decide if a term should be dropped from a model is if the estimated degrees of freedom (EDF) for the term are close to their lower limit. What would be the

Dear list, I?m using the ?mgcv? package to fit some GAMs. Some of my covariates are derived quantities and have an associated standard error, so I would like to incorporate this uncertainty into the GAM estimation process. Ideally, during the estimation process less importance would be given to observations whose covariates have high standard errors. The gam() function in the ?mgcv? package

Hello R list, I need to compute empirical variograms using data from a large geographic area (~10^6 km2). Although I could not find a specific reference, I assume that both geoR and gstat calculate distances among data points assuming points are on a flat surface (using the Pythagorean Theorem). Because the location of my data is large and located near the pole, assuming that latitude and

Hello fellow R's, I do apologize if this is a basic question. I'm doing some GAMs using the mgcv package, and I am wondering what is the most appropriate way to determine how much of the variability in the dependent variable is explained by each term in the model. The information provided by summary.gam() relates to the significance of each term (F, p-value) and to the
