This only builds a yacas command.
You need to also call yac_str(), yac_expr() or similar.
This is the reason that it does not call yacas: it depends on how you
want it returned (string, expression).
y_rmvars(x)
Arguments
x
yacas command
Examples
cmd<-"{x == 2, y == 4}"yac_str(cmd)#> [1] "{x==2,y==4}"yac_str(y_rmvars(cmd))#> [1] "{2,4}"
