Hi all,
I need to create a data.frame from a variable number of vectors.
The number of these vectors could change so I need a dinamic way to
group all in a data.frame. The number is length(abc).
e.g. vectors in my workspace
N1 -c(1,2,3,4)
N2 -c(1,2,3,4)
N3 -c(1,2,3,4)
abc -c(1,2,3)
the
one way is:
N1 - rnorm(4)
N2 - rnorm(4)
N3 - rnorm(4)
N4 - rnorm(4)
X1 - LETTERS[1:4]
###
nams - c(paste(N, 1:4, sep = ), X1)
dat - data.frame(lapply(nams, get))
names(dat) - nams
dat
# check also
sapply(dat, data.class)
I hope it helps.
Best,
Dimitris

data.frame(OneVector, TwoVector,
sapply(apropos(^N[0-9]*$), get, simplify = FALSE))

Your expression is trying to sum a character vector
containing the names of the variables that begin with ABC.
Try this and try executing each portion of it to understand
it better:
ABC1 - ABC2 - 1
