RE: Combine many variables into a data frame

2013-05-19T23:35:16

The most direct way could be just to use a loop.  Assuming your variables are all the same mode, e.g. numeric, it might be useful to put them into a matrix first:

M <- matrix(0, length(v1), 1000)
for(j in 1:1000) M[, j] <- get(paste("v", j, sep=""))

M <- as.data.frame(M)

There are other more slick ways of doing it using language manipulation, but that way you might start to put a strain on the parser, anyway.

URGENT HELP NEEDED !!!

GRAHAM LEASK — 2013-04-26T06:44:21

I do hope you get this fast, I came down to Manila, Philippines with my 
family for a short vacation, unfortunately we got mugged at the park of 
the hotel where we stayed. They stole our cash, credit cards and 
cellphones, but thank God we still have our lives and passports. The  
hotel manager has been unhelpful to us for reasons I don't know and I'm 
writing to you from a local library.

I've reported the situation 
to the police and after writing down some statements, I've not heard 
from them. I contacted the  consulate and all I keep hearing is that 
they will get back to me. Our return flight leaves soon, I need you to 
help me out  with a quick loan to settle our bills here so we can get 
back home. I'll refund the money as soon as we return home safely.

We look forward to hearing from you!.
