Hello,
I would like to get an advice on how the notorious eval(parse()) construct
could possibly
be avoided in the following example. I have an array x, which can have
different number of dimensions,
but I am only interested in extracting, say, the first element of the first
dimension. Currently I achieve this
in this way:
eval(parse(text=paste0("x[1", paste(rep(", ", length(dim(x)) - 1),
collapse=""), "]")))
Is it possible to avoid the eval parse here? How?
Best regards,
Martin
