rvec

Tools for working with random draws, including draws from asimulation or Bayesian analysis. The main data structure is anrvec, which holds multiple draws but which behaves (mainly)like a standard R vector.

Installation

install.packages(rvec)

Example

library(rvec,warn.conflicts =FALSE)library(dplyr,warn.conflicts =FALSE)

Create anrvec.

x<-rvec(rbind(c(10,11),c(100,101),c(1000,1001)))x#> <rvec_dbl<2>[3]>#> [1] 10,11     100,101   1000,1001

Perform arithmetic on it.

x+1#> <rvec_dbl<2>[3]>#> [1] 11,12     101,102   1001,1002

Put it in a tibble.

df<-tibble(g =c(1,2,1), x)df#> # A tibble: 3 × 2#>       g         x#>   <dbl> <rdbl<2>>#> 1     1     10,11#> 2     2   100,101#> 3     1 1000,1001

Manipulate it in a tibble.

df%>%group_by(g)%>%count(wt = x)#> # A tibble: 2 × 2#> # Groups:   g [2]#>       g         n#>   <dbl> <rdbl<2>>#> 1     1 1010,1012#> 2     2   100,101

Summarise it.

draws_mean(x)#> [1]   10.5  100.5 1000.5
