Create an Rvec from Data

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)

Arguments

x

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

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"

Details

Class "rvec" has four subclasses, each dealing with a diffent type:

• "rvec_dbl" doubles

• "rvec_int" integers

• "rvec_lgl" logical

• "rvec_chr" character

An rvec may have zero elements, but must have at least one draw.

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)
#> <rvec_dbl<3>[2]>
#> [1] -1.5,2,0.2 -2.3,3,1.2

l <- list(rpois(100, lambda = 10.2),
          rpois(100, lambda = 5.5))
rvec(l)
#> <rvec_int<100>[2]>
#> [1] 10 (5.5, 17) 5 (1.5, 11) 

rvec(letters[1:5])
#> <rvec_chr<1>[5]>
#> [1] "a" "b" "c" "d" "e"

l <- list(a = c(TRUE, FALSE),
          b = c(FALSE, TRUE))
rvec(l)
#> <rvec_lgl<2>[2]>
#>   a   b 
#> T,F F,T
