pokerstoveR

An R wrapper around the ps-eval executable from pokerstove.

Installation

This package is not on CRAN. You can however install the development version with install_github.

devtools::install_github("GregorDeCillia/pokerstoveR")

In order to use the package, pokerstove has to be installed and ps-eval has to be in the PATH.

Preflop equities

Currently, there is just one useful command in the package which is called ps_eval. This command relies on ps-eval to calculate equities of NLHE hands.

library(pokerstoveR)
ps_eval("AcAs", "2h7d")
#>   hand  equity    wins ties
#> 1 AcAs 87.4224 1493820 3118
#> 2 2h7d 12.5776  212248 3118

In this case we see the preflop equities of the hands AcAs (ace of clubs, ace of spades) versus 2h7d (two of hearts, seven of diamonds). The aces have 87.4224% equity.

The command ps_eval can be called with an arbitrary number of hands. However, the number of hands has to be at least two.

ps_eval("AcAs", "2h7d", "KsKd", "7h8h")
#>   hand   equity   wins    ties
#> 1 AcAs 58.56780 635560   490.5
#> 2 2h7d  5.14126  43871 11963.5
#> 3 KsKd 16.97710 183882   490.5
#> 4 7h8h 19.31390 197787 11963.5

Postflop equities

To calculate the postflop equities, a board has to be specified using the board parameter of ps_eval.

ps_eval("AcAs", "2h7d", board = "2c2d2s")
#>   hand   equity wins ties
#> 1 AcAs  0.10101    1    0
#> 2 2h7d 99.89900  989    0
