Hello,If you do this after the for loop, you'll get what you want:
paste(tre,collapse=)
(you can use whatever separator you want in the collapse argument)
But you don't even need the for loop, just do this instead of the for loop:
paste(con(,p, == ,c,, ,zest,, ,sep=,collapse=)
Best,Miguel

Dear forum:
I've been trying like for hours but I cannot solve this. I wonder if you could
give me a hand.
I would like to combine the following elements of an array which I must
generate in order to get the syntax I need for another software, lets say:
c-c(1:7)
zest-c(12,34,45,132,56,23,6)
p-[foresnat2]
for(i in 1:7){tre[i]-paste(con(,p, == ,c[i],, ,zest[i],, ,sep=)}
[1] con([foresnat2] == 1, 12,
[1] con([foresnat2] == 2, 34,
[1] con([foresnat2] == 3, 45,
[1] con([foresnat2] == 4, 132,
[1] con([foresnat2] == 5, 56,
[1] con([foresnat2] == 6, 23,
[1] con([foresnat2] == 7, 6,
I would like the elements of the object tre to go one after another without
space (or with a character I design like for example * or + )like this:
[1] con([foresnat2] == 1, 12, con([foresnat2] == 2, 34, con([foresnat2] == 3,
45, con... etc
I understand it could be done with the function paste invoking each of the
elements, but lets say they are not only 7 but 20 or 40 elements...
Is it possible? What can I do?
Thank you very much in advance.
Luis Vega
PD: Just in case: For the other software language i was talking about, the
usage of con is the same as ifelse in R, I'm trying to generate
a large embed ifelse(..., ..., ifelse(...,...,ifelse( entry. but with
what I'm requiring lines above should be enough I think.
