rvec (version 0.0.7)

rvec: Create an Rvec from Data

Description

Create an object of class "rvec", based on input data.

Usage

rvec(x)
rvec_chr(x = NULL)
rvec_dbl(x = NULL)
rvec_int(x = NULL)
rvec_lgl(x = NULL)

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"

Arguments

x

A matrix, a list of vectors, an atomic vector, or an rvec.

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; or

• an rvec.

See Also

• new_rvec() Create a blank rvec.

• collapse_to_rvec() Create rvecs within a data frame.

• rnorm_rvec(), rbinom_rvec(), etc. 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)
