Hi All, I need to write as text files 1000 ish variation of the same data frame, once I permute a row. I would like to use the function write.table() to write the files, and use a loop to do it: for (i in 1:1000){ bb8[2,] = sample(bb8[2,]) write.table(bb8, quote = F, sep = '\t', row.names = F, col.names = F, file = 'whatever?????.txt') } so all the files are called

Dear users, *******I have a function f to simulate data from a model (example below used only to show my problems) f<-function(n,mean1){ a<-matrix(rnorm(n, mean1 , sd = 1),ncol=5) b<-matrix(runif(n),ncol=5) data<-rbind(a,b) out<-data out} *********I want to simulate 1000 datasets (here only 5) so I use S<-list() for (i in 1:5){ S[[i]]<-f(n=10,mean1=0)} ******I have a

Hi all, I am trying to debug an error of a function g defined and used inside another function f of a package. So I have f <- function(whatever){ ... g <- function(whatever2){ ... } ... } If I wanted to debug some thing directly inside f I would do debug(f). But this does not go inside g code. On the other hand, debug(g) does not work as g is not a defined function in the

Thank you Ivan, your example solves my issue this time through debug(environment(Adder$add)$add) Just for the future, you say Moreover, `g` doesn't exist at all until f() is evaluated and reaches this point. If `f` was a function, it would be possible to trace() it, inserting a call to debug(g) after it's created. How should I call trace() if f was a function? Best

I would like to create a new dataframe from the DateTime column of an existing dataframe and a numeric vector. When I do cbind(x[,1], y) the result is: [1,] 1199370600 12.500 [2,] 1199371200 69.375 [3,] 1199371800 23.750 where the first column you see used to look like: "2008-01-03 08:30:00 Central Standard Time" "2008-01-03 08:40:00 Central Standard Time"

How do I limit the length of an extension? In my test IVR/Automated Attendant (whatever it's called), at the beginning it plays "if you know your parties 3 digit extension, you may enter it now) and then it gives a list of options. If the caller puts the 3 digit extension, it goes through fine, if they press 1, or 2 it goes to the selected menu option, but if they dial 91235551212 it

I create users from an administration controller, but I don''t want to fill in all their information fields, just have their name and email address. When they accept the invitation, I want to implement validation on the other fields. I have looked at using :on => :update, but I would have to make the

This has been driving me crazy for a few days now. I am using sqlite3 however I have also found this to be the case with 2.8.15: I have data types text or integer on every column of every table in the database.
