Hi Ashta, There are many ways to do it.

Hi all, In a data set I have group(GR) and two variables x and y. I want to remove a group that have the same record for the x variable in each row. DM <- read.table( text='GR x y A 25 125 A 23 135 A 14 145 A 12 230 B 25 321 B 25 512 B 25 123 B 25 451 C 11 521 C 14 235 C 15 258 C 10 654',header = TRUE, stringsAsFactors = FALSE) In this example the output should contain group A and

Hi all, I am trying to do wavelets and I got an error message saying "The length of data is not a power of 2" Is there a way of handing that? or should the data length be exactly the power of 2? I am using R version 2.9.2 (2009-08-24) The is library(wavethresh). wds <- wd(ds$v,filter.number=1) Thanks

HI R-Users Assume that I have a data frame 'temp' with several variables (v1,v2,v3,v4,v5.). v1 v2 v3 v4 v5 1 2 3 3 6 5 2 4 2 0 2 -9 5 4 3 6 2 1 3 4 1, I want to look at the entire row values of when v2 =-9 like 2 -9 5 4 3 I wrote K<- list(if(temp$v2)==-9)) I wrote the like this but it gave me which is not correct.

Hi all, I am using R to extract data on a regular basis. However, sometimes using the same script and the same data I am getting different observation. The library I am using and how I am reading it is as follows. library(stringr) namelist <- file("Adress1.txt",encoding="ISO-8859-1") Name <- read.fwf(namelist, colClasses="character",
