._1 <- 1:1

nmmp1 <- n - m + ._1

while (a[1] != nmmp1) {

if (e < n - h) { h <- ._1 e <- a[m] j <- ._1 } else { e <- a[m - h] h <- h + ._1 j <- 1:h } a[m - h + j] <- e + j r <- if (nofun) x[a] else FUN(x[a], ...) if (simplify) out[, i] <- r else out[[i]] <- r i <- i + 1

}

I wonder what is the meaning of the statement "._1 <- 1:1".
First question: what is the difference with "._1 <- 1"?
Second question (perhaps answerd by the answer to the first): why not
using "1" directly? E.g.:

*[...]
*

h <- 1 e <- a[m] e <- 1

Sorry if this is covered by the manuals, but it's not easy to search
for the string "._1" with the usual search engines.
Thank you!
