ysym without quotes (for the lazy)

[hojsgaard]

Typing the quotes in eg ysym is extra work. How about allowing something like

library(Ryacas)

ysym2 <- function(s){
s_ <- substitute(s)
s2 <- as.character(s_)
ysym(s2)
}

ysym3 <- function(s){
s_ <- substitute(s)
s2 <- as.character(s_)
assign(s2, ysym(s2), envir = .GlobalEnv)
}

Giving

a <- ysym2(a)
a
y: a
ysym3(b)
b
y: b

If this were done it would be important that it be separate from ysym with both available. Look at the mess tidyverse got itself into requiring rlang and all its associated complexity.
