R help - Apr 2009 - Processing POST data with brew?

Heya Folks,

I've got to process a form that contains variable series of values,
which i want to collect into a vectors.

Say the first series has ten values, with id's ranging from X1 to X10,
currently i process them in the following hardcoded manner:

x1 <- c(as.numeric(POST$X1), as.numeric(POST$X2), as.numeric(POST$X3),
as.numeric(POST$X4), as.numeric(POST$X5), as.numeric(POST$X6),
as.numeric(POST$X7), as.numeric(POST$X8), as.numeric(POST$X9),
as.numeric(POST$X10))

Is there a way to process these in a loop?

Mazzel,

Martijn.

I guess unlist helps:

x1 <- as.numeric(unlist(POST))

but hard to be sure without seeing the original object for which
str(POST)
would have been helpful.
