Try this:
sum(a * c(100, 10, 1)) + sum(b * c(10, 1))

Hi AD,
You might try the following:
# data
a <- c(2,3,5)
b <- c(8,7) # you got this wrong ;)
# option 1
foo <- function(x) as.numeric(paste(x, sep = "", collapse = ""))
# examples
foo(a)
# [1] 235
foo(b)
# [1] 87
foo(a) + foo(b)
# [1] 322
# option 2
foo2 <- function(x, y) foo(x) + foo(y)
#
I am trying to create a function that is able to calculate this sum:
a<-c(2,3,5)
b<-(8,7)
with "a" meaning 235 and "b" 87. So the result of this sum would be 235 + 87
= 322.
a <- c(2,3,5)
b <- c(8,7)
vectorToScalar <- function(x) {
as.numeric(paste(x, collapse = ""))
}
vectorToScalar(a)
