similar to: conditional grouping of variables: ave or tapply or by or???

Hi R users, I would like to add year information to each point in a scatter plot. The following example shows what i mean: df=data.frame(year=c(2001,2002,2003),a=c(8,9,7),b=c(100,90,95)) df plot(b~a,data=df) Now, I would like to see which point belongs to 2001, 2002 and 2003 in the above graphic. Thank you very much, ozan [[alternative HTML version deleted]]

Dear All, I am economist and working on poverty / income inequality. I need descriptive statitics like the ratio of education expentitures between different income quintiles where each household has a different weight. After a bit of google search I found 'Hmisc' and 'quantreg' libraries for weighted quantiles. The problem is that these packages give me only weighted quintiles;

Hi R-users, I would like to calculate weighted mean of several variables by two factors where the weight vector is the same for all variables. Below, there is a simple example where I have only two variables: "v1","v2" both weighted by "wt" and my factors are "gender" and "year". set.seed(1) df <- data.frame(gender = rep(c("M",

Hi As you may''ve seen from my last posts I''m struggling to get the setup on my subject line to work without flaws. I''ve tried compiling the Kernel from Source, I''ve also tried Fedora 14, which has a flaky pv_ops Dom0 kernel which DOESN''T work at all, but none of these seem to work. I''m a mid-time XEN user, I just love it and want to stay

Hi, I was wondering if there is an easy way to accomplish the following in R: Often I want to apply a function, e.g. weighted.quantile from the Hmisc package to grouped subsets of a data.frame (grouping variable) but then I also need to hand over the weights which seems not possible with summaryBy or aggregate or the like. Is there a function to do this? Currently I do this with loops but it

Hi, I am having trouble using the ave function with a POSIXct object. For example: x<-Sys.time()+0:9*3600 dat<-data.frame(id=rep(c('a',' b','c'),each=10),dt=rep(x,3),i=rep(1:10,3)) dat # This is what I want to do: dat$time.elapsed<-unsplit(lapply(split(dat$dt,dat$id),function(x) x-x[1]),f=dat$id) dat # The above code does the trick, but from the standpoint of

Dear list, # I have a DF like this: sleep$b <- c(rep(8,10), rep(9,10)) sleep$me <- with(sleep, ave(extra, group, FUN = mean)) sleep # I would like to create a new variable # holding the b-th value of group 1 and 2. # This is not what I want, it takes always the '8' from group '1' # and not the '9' sleep$gr <- with(sleep, ave(extra, group, FUN = function(x)

DearR Users, I have a problem which I think you might be able to help. I have a dataframe which I'm trying to "filter" following different groups I specified. It's a little hard to explain, so here is an example: My dataframe: ESS DHP 1 EPB 22 2 SAB 10 3 SAB 20 4 BOJ 14 5 ERS 28 11 SAB 10 12 SAB 22 13 BOJ 26 20 SAB 10 21 SAB 22 22 BOJ 32 29 SAB 14 30 SAB

Hi, can anyone tell me how to nest two fixed factors using glmer in lme4? I have a split-plot design with two fixed factors - A (whole plot factor) and B (subplot factor), both with two levels. I want to do GLMM as I also want to include different plots as a random factor. But I am interested on the effect of A a B and their interaction on the response variable. I tried

Hi guys, I have two data frames: one referred to 2008 and one to 2009. Their structure is identical except for the different data in them. I need to create a vector alfa of the same length of the dataframe 2009 and fill each element with the mean of 2008$var1 conditional to the subgroup indicated by a factor variable in 2009$var2. In this case it would be easy to use the function

Dear R-ers, In my question there are no statistics involved - it's all about data manipulation in R. I am trying to write a code that should replace what's currently being done in SAS and SPSS. Or, at least, I am trying to show to my colleagues R is not much worse than SAS/SPSS for the task at hand. I've written a code that works but it's too slow. Probably because it's

Unable to resolve error in seq.default(which(text == "")[1] + 1, length(text), 1): wrong sign in 'by' argument I am trying to run this code get.msg <- function(path) { con <- file(path, open = "rt", encoding = "latin1") text <- readLines(con) # The message always begins after the first full line break msg <- text[seq(which(text ==

Hello, I'm using the rmeta package to perform a meta analysis using summary statistics rather than raw data, and would like to analyze the effects in three different subgroups of my data. Furthermore, I'd like to plot this on one forest plot, with corresponding summary weighted averages of the effects displayed beneath each subgroup. I am able to generate the subgroup analyses by simply

Hi, Is there is any way in ruby on rails where we show all my groups there subgroups with check boxes in tree structure way? e.g group A | ----Group A.1 | ----Group A.2 | ---------Group A.2.1 All with check boxes and subgroup opens when click on root ? -- Posted via

Hi there, Could someone help me with the following programming problem..? I have written a function that works for my intended purpose, but it is quite closely tied to a particular dataframe and the names of the variables in this dataframe. However, I'd like to use the same function for different dataframes and variables. My problem is that I'm not quite sure how to tell my function in
