Exe: Execute Yacas Expression using Ryacas

In jeksterslab/yacR: Utilities for Using Ryacas

Description

Executes Yacas expressions using Ryacas with different output options.

Usage

Exe(x, R = FALSE, format = "ysym", simplify = FALSE)

Arguments

x	Character string. Yacas expression.
R	Logical. If R = TRUE, returns symbolic result as an R expression. If R = FALSE, returns symbolic result as "ysym", "str", or "tex" depending of format.
format	Character string. Only used when R = FALSE. If format = "ysym", returns symbolic result as yac_symbol. If format = "str", returns symbolic result as a characetr string. If format = "tex", returns symbolic result as LaTeX math.
simplify	Logical. Simplify symbolic results.

Examples

A <- Ryacas::ysym(
  matrix(c("a", "c", "b", "d"), ncol = 2)
)
x <- paste0("Determinant(", A, ")")
Exe(x, R = FALSE, format = "ysym")
Exe(x, R = FALSE, format = "str")
Exe(x, R = FALSE, format = "tex")
Exe(x, R = TRUE)

a <- 1
b <- 2
c <- 3
d <- 4
eval(Exe(x, R = TRUE))

# `det.yac_symbol` from `Ryacas`
Ryacas::det(A)

# `det` from `base` R

A <- matrix(c(a, c, b, d), ncol = 2)
det(A)
