This is a regression. Still haven't quite nailed down an MRE but it's do do with using a variable in j from the same environment, which is causing the eval used for https://github.com/Rdatatable/data.table/issues/4159 to fail.

[hongyuanjia]

I am the author of eplusr package. Maybe I can help to provide a MRE here. But I did not know how to install the version that cause this error. Can I directly install the dev version of data.table via remote::install_github("Rdatatable/data.table")?

[eddelbuettel]

@hongyuanjia That is correct. The release candidate version in current development is in the main branch, and with that install_github() call you will get it.

[MichaelChirico]

Thanks @hongyuanjia , yes the latest dev reproduced the error for me. However it stopped reproducing as the eplusr vignette stopped compiling. I think maybe I was pinging GitHub to download the EPlus binary a few too many times

[eddelbuettel]

I think maybe I was pinging GitHub to download the EPlus binary a few too many times

I can recommend registering a GITHUB_PAT and setting it as an environment variable.

[hongyuanjia]

Below is a MRE. Seems like a scoping issue:

library(data.table)

dt <- data.table(id = c(1, 1, 2), value = c("a", "b", "c"))

fun <- function (dt, tag = c("A", "B")) {
    dt[, var := tag[[.GRP]], by = "id"]
}

fun(dt)
#> Error in eval(call("is.atomic", jsub[[2L]]), envir = x): object 'tag' not found

^{Created on 2020-07-20 by the reprex package (v0.3.0)}

[hongyuanjia]

Interesting. Inside [.data.table, [[ does not work but [ does:

library(data.table)

dt <- data.table(id = c(1, 1, 2), value = c("a", "b", "c"))

fun1 <- function (dt, tag = c("A", "B")) {
    # using "[[" does not work
    dt[, var := tag[[.GRP]], by = "id"]
}

fun1(dt)[]
#> Error in eval(call("is.atomic", jsub[[2L]]), envir = x): object 'tag' not found

fun2 <- function (dt, tag = c("A", "B")) {
    # using "[" works
    dt[, var := tag[.GRP], by = "id"]
}

fun2(dt)[]
#>    id value var
#> 1:  1     a   A
#> 2:  1     b   A
#> 3:  2     c   B

[hongyuanjia]

The error comes from:
https://github.com/Rdatatable/data.table/blob/1a8a39074e73a857f95f628ba0c26d820b0cee39/R/data.table.R#L1545

where [.data.table tries to evaluate the name inside the data.table.

[hongyuanjia]

I can confirm that all errors are caused by this issue. After I temporarily getting workaround on this, all check errors are gone and eplusr can work well with dev version of data.table.

[MichaelChirico]

Thanks @hongyuanjia for the MRE. I do think data.table should be able to work without any change on your end in this case. It is a bug introduced by the fix for #4159.

[ColeMiller1]

@MichaelChrico I looked into this - it looks like simply adding enclos = parent.frame() within the eval statement fixes the issue. I recompiled and the (great!) MRE no longer errors and there are no tests that fail on our end. Not sure why it works, that should be the default enclosure.

[MichaelChirico]

Thanks @ColeMiller1 I had tried that but I only tried it on a non-MRE so it didn't work. Glad it's as easy as that.

eval's default is parent.frame() here, but when that parent.frame() is evaluated, it's within eval. We need it to be parent.frame(), evaluated from within j. I think.
