rvec {rvec} | R Documentation |
Create an Rvec
Description
Create an Object of Class "rvec"
.
Usage
rvec(x)
rvec_chr(x = NULL)
rvec_dbl(x = NULL)
rvec_int(x = NULL)
rvec_lgl(x = NULL)
Arguments
x |
A matrix, a list of vectors, or an atomic vector. |
Details
Class "rvec"
has four subclasses, each dealing with
a diffent type:
-
"rvec_dbl"
doubles -
"rvec_int"
integers -
"rvec_lgl"
logical -
"rvec_chr"
character
These subclasses are analogous to double()
,
integer()
, logical()
, and character()
vectors.
Function rvec()
chooses the subclass, based on
x
. Functions rvec_dbl()
, rvec_int()
,
rvec_lgl()
, and rvec_chr()
each create
objects of a particular subclass.
x
can be
A matrix, where each row is a set of draws for an unknown quantity.
A list, where each element is a set of draws.
An atomic vector, which is treated as a single-column matrix.
Value
An rvec with the following class:
-
rvec_dbl()
:"rvec_dbl"
-
rvec_int()
:"rvec_int"
-
rvec_lgl()
:"rvec_lgl"
-
rvec_chr()
:"rvec_chr"
-
rvec()
:"rvec_chr"
,"rvec_dbl"
"rvec_int"
, or"rvec_lgl"
, depending ontypeof(x)
.

collapse_to_rvec()
creates rvecs within a data frame. Random variate functions such as
rnorm_rvec()
andrbinom_rvec()
can be used to create rvecs representing probability distributions.
Examples
m <- rbind(c(-1.5, 2, 0.2),
c(-2.3, 3, 1.2))
rvec_dbl(m)
l <- list(rpois(100, lambda = 10.2),
rpois(100, lambda = 5.5))
rvec(l)
rvec(letters[1:5])
l <- list(a = c(TRUE, FALSE),
b = c(FALSE, TRUE))
rvec(l)
