Cannot use the symbol i to subset an array

[vtspaid]

Hello again @pvanlaake , I appreciate the new updates to the package. The package seems to be in a pretty good place. I have noticed a couple small bugs that I can easily work around but I wanted to bring to your attention.

The first one is that using i as a symbol when trying to access data in an array produces unexpected results. i is always given the value of it's position. i.e. in x[i, ,] i is always treated as 1, and in in x[, i, ] i is always treated as 2. It's perhaps unusual to use i in this way but I found it out when trying to access elements within a for loop.

x <- array(1:100, c(5, 5, 4))
z <- as_zarr(x)
myarray <- z[["/"]]

i <- 4
myarray[i, i, i]
myarray[1, 2, 3]

# Works as expectd
for (j in 1:5) {
  print(myarray[j, 1:5, 1])
}

# Does not work as expected
for (i in 1:5) {
  print(myarray[i, 1:5, 1])
}

Same problem as in #13: A wrong environment was being called. In this case the argument i did exist in the environment and so the function completed, but it obviously had a wrong value. Note that you could have used any argument name that did not exist in the environment that was being used because R's scoping rules traverse up the chain of environments until a match is found.

Fixed in commit ae94e09.
