lget
or lgetElement
applies
getElement
to a
list using lapply
. sget
and
sgetElement
do the same thing with
sapply
.
lget(X, name) lgetElement(X, name) sget(X, name, simplify = TRUE, USE.NAMES = TRUE) sgetElement(X, name, simplify = TRUE, USE.NAMES = TRUE)
X |
A list. |
name |
A literal character string or a name (possibly backtick
quoted). For extraction, this is normally (see under
‘Environments’) partially matched to the |
simplify |
logical or character string; should the result be
simplified to a vector, matrix or higher dimensional array if
possible? For |
USE.NAMES |
logical; if |
A list (lget
) or vector (sget
)
of the same length as X
with the
name
parts of each element of X
.
e1 <- list( x = rnorm(5), y = letters[c(1:2, 2:1, 3)], z = c(TRUE, TRUE, FALSE, TRUE, TRUE) ) e2 <- list( x = rnorm(5), y = letters[c(1:4, 1)], z = c(FALSE, TRUE, FALSE, TRUE, FALSE) ) X <- list(e1, e2) lget(X, name = "x") sget(X, name = "y")
