I am working on translating the word search algorithm implemented in both Julia (for the main code -- https://rosettacode.org/wiki/Word_search#Julia) and Python (for the creation of the class for Grid -- https://rosettacode.org/wiki/Word_search#Python).
I am attempting to rewrite the class definition of Grid from Python (see below) into R:
class Grid:
def __init__(self):
self.num_attempts = 0
self.cells = [['' for _ in range(n_cols)] for _ in range(n_rows)]
self.solutions = []
The following is my attempt at translating the Python class into an R6 class:
library("R6")
Grid <- R6Class("Grid",
public = list(
num_attempts = NULL,
cells = NULL,
solutions = NULL,
initialize = function(num_attempts = NA, cells = NA, solutions = NA) {
self$num_attempts <- 0
self$cells <- cells
self$solutions()
},
cells = function(val) {
for (val in seq_along(ncols)) {
for (val in seq_along(nrows))
{
result <- vector("character")
result
}
}
}
)
)
The following is the error message that I receive in R:
Error in R6Class("Grid", public = list(num_attempts = NULL, cells = NULL, :
All items in public, private, and active must have unique names.
Please offer suggestions on how to correctly perform this translation.
Thank you.
