similar to: loop through files and create object

Good day, For lack of a better solution (or perhaps I am ignorant to something more elegant), I have been bootstrapping panel data by hand so to speak and I would like to know if there is a way to define multiple variables in a loop using the loop variable. I found a post (here: https://stat.ethz.ch/pipermail/r-help/2002-October/026305.html ) that discussed naming multiple variables but it

The text below is a part of, some work I have to do, which is due in 2 days and I am strung up with a lot of other stuff, so I was hoping someone would take 5 mins and help me ?? Here is a part of my data.frame: year country1 country2 contig comlang pop1 gdp1 pop2 gdp2 rta dist avgflow 1 1992 AUS AUT 0 0 17.4950008 321708.281

Hi I have a data.set with 7 lists, with over 7000 observations in each list. to of the lists contain country names. like: aus dnk fra aus usa aut itl usa . . . etc. My dilemma is that I want to add an extra column/list to my data.set. If the countries are both european it should be assigned 1 or true AND if one or both the countries are non-european it should be assigned 0 or false.

Hello all, Sorry if this question has been answered in the past, but I could not find an answer. I am trying to print quotes within a cat output. The arguments are: file= "Data labels" directory= "/home/mylaptop/" The function returns: cat("The file", file, "is located in directory", directory, sep=" ") The output R prints is The file Data

Hello, This is a beginner question. I am trying to loop through numbered variables with "apply" to calculate weighted means. My data is "data", the variables are "var1" to "var100", the weight is "weight". The command works using sapply(paste('data$var', 1:100, sep=''), function(x) weighted.mean(eval(parse(text=x)), data$weight))

I saw different specifications for Random Effects and I'm confused about the use of "/" and the use of "(0+...|)" . Let say we have a nested structure where some countries have some several plants in different states and we measure the reaction to a drug. The list of Countries = USA, France, Italy The States for USA = Michigan, Florida, California The States for France

Dear all I have a model that looks like this: m1 <- lmer(Difference ~ 1+ (1|Examiner) + (1|Item), data=englisho.data) I know it is not possible to estimate random effects but one can obtain BLUPs of the conditional modes with re1 <- ranef(m1, postVar=T) And then dotplot(re1) for the examiner and item levels gives me a nice prediction interval. But I would like to have the prediction

Dear all, I want to estimate a crossed-random-effects model (i.e., measurements, students, schools) where students migrate between schools over time. I'm interested in the fixed effects of "SES", "age" and their interaction on "read" (reading achievement) while accounting for the sample design. Based on a previous post, I'm specifying my model as: fm1 <-

Hello, I would like to read sets of files within a folder, perhaps using recursive methods. Right now, I rename the files before import. It would be even better to do this without renaming files, without providing explicit filenames, perhaps by importing files based on chronology, and translating each filename into a header? Please excuse my ignorance, and help cure my clunky programming

Sorry, my question is if exists a command tkexit in R, i need a command how exit of tcl for close an aplication. How to use him. Thank

dear all, I'm a newbie in map tools. I was asking to perform an apparently very simple task. I have a list of countries (about fifty all over in the world) scored with a real positive value. Eg Country score Italy .56 UK .58 Korea .41 Mexico .63 ... I wish to plot geographical maps where every country is filled with a color depending on his score. Using maptools library and

I am choosing a file like this: #Bring up file selection box fn<-file.choose() fp<-file.path(fn,fsep='\\') Unfortunately, the file path contains the short file name and extension as well. I had hoped to get only the path so I could make my own long filenames (for output graphs) by concatenation with this file path. Of course I can split the string and assemble the components from

Dear R-list, Sorry for spamming the list lately, I am just learning the more advanced aspects of R! I have some data that looks like this: Out Country1 Country 2 Country 3 ... CountryN 1 1 1 1 1 0 1 1 0 1 1 1 0 1 0 I want to create a new variable that counts the number of zeros in every row whenever Out is equal to 1, and else it is a zero, so it would look like this: new_var 0 0 2 I

In the particular application I have I save "test.Rdata" to a sub directory dir<-"Example" dir.create(dir) test<-data.frame(a=c(1,2,3),b=c(3,4,5) full<-file.path(dir,"test.Rdata,fsep=.Platform$file.sep) save(test,file=full) load(full) returns NULL it works fine when the object is saved to the working directory, but fails when saved to a sub directory.

So either: XX contains some non-finite numbers Or Something produced from it does. Non finite means things like 1?0. R might show Inf or -Inf. But if there is maths happening in the function it might be passing something to it the is a 0 and so creating a Inf. But if there is a test of is.finite you will get "false" to NA or 0/1 or "0" (ie. Passing a character
