Hi, I am trying to create a data frame using the dimensions of another data frame that I have input. This is the code I am using: tab is the data frame that is input. c.leng<-length(tab[,1]); r.leng<-length(tab[1,]); opdf<-data.frame(ncol=c.leng, nrow=r.leng); a<-1; while(a<=c.leng) { opdf[[1]][a]<-tab[[1]][a]; a<-a+1; } This is the error message I am getting: Error in `[[<-.data.frame`(`*tmp*`, 1, value = c(4626L, 1L)) : replacement has 2 rows...

I know this is a bit long but I can't seem to find the errors so I would appreciate your help :) This is my program : files<-Sys.glob("*.rescount.txt");length<-length(files);* #selecting all files of a particular extension, saving in a list* a<-1; while(a<=length) *#going through every element of the list* { df1<-read.table(files[a]); c.leng<-length(files[,1]); r.leng<-length(files[1,]); *#creating data frame for output with the...

Colleagues, I am trying to de-duplicate a large (long) database (approx 1mil records) of diagnostic tests. Individuals in the database can have up-to 25 observations, but most will have only one. IDs for de-duplication (names, sex, lab number...) are patchy. In a first step, I am using Andreas Borg's excellent record linkage package (), that leaves me with a list of 'pairs' looking

I gratefully appreciate any advice and suggestion on how to obtain the desired data matrices/ dataframes from this data file in R.

...g a baffling behaviour of stepAIC(), and I hope to get any advice/help on what went wrong or I'd missed. I greatly appreciate any advice given. I am using stepAIC() to, say, select a model via stepwise selection method. R Version : 1.7.1 Windows ME Many thanks and best regards, Siew-Leng ***Issue : When stepAIC() is placed within a function, it seems that stepAIC() cannot detect the data matrix, and the program is halted as a result. However, when the same codes are copied, paste and run in R workspace, stepAIC can execute and R is able to produce the desired output....

Hi, I would like to generate a correlation matrix with a particular structure. For example, a 3n x 3n matrix : A_(nxn) aI_(nxn) bI_(nxn) aI_(nxn) A_(nxn) cI_(nxn) aI_(nxn) cI_(nxn) A_(nxn) where - A_(nxn) is a *specified* symmetric, positive definite nxn matrix. - I_(nxn) is an identity matrix of order n - a, b, c are (any) real numbers Many attempts have been unsuccessful because a

...;t just figure out? Thanks in advance for any suggestions. A reproducible example: foo <- as.list(Sys.time()+1:10) sapply(foo, "[", 1) I've also noticed that trunc.POSIXt does something unexpected (to me) in some cases: foo <- as.POSIXct("2011-03-25 21:03:20")+1:10 length(foo) ## obviously 10 length(trunc(foo, "day")) # 1! This makes it impossible to use [ and length() with trunc'ed POSIXct vectors (and it is a little unexpected too that the result of using trunc with a POSIX_ct_ object is a POSIX_lt_ object) but the cure seems easy: in the code of...

Does anyone have suggestions on how I could improve my function?...

I have a new problem: Register RBP is used in a function foo. (I am not allocating RBP to any virtual register, the instances of RBP in function foo are in the machine code when my register allocator starts.) Function foo calls function bar. Register RBP is not saved across the call, though it is live after the call. Function bar includes a virtual register. The code that I'm using to
