Error: `.x` is empty, and no `.init` supplied

[slowkow]

Hi Miles,

Thanks for the great package! Just like datapasta, this is brilliant. RStudio ought to have these packages installed by default.

Anyway, I ran into an error and I'm not sure how to fix it. Any advice is welcome.

Here is the full contents of temp.R:

library(shiny)
library(shinysky)
library(ggplot2)
library(scales)
library(viridis)
library(Matrix)
library(egg)
library(parallel)
library(pheatmap)

Here is what happens if I try your function:

> deplearning::depl_check("temp.R")
[deplearning] Starting dependency check.
[deplearning] Scanning file temp.R done.

same here. looks like it's in a call to get_gh_pkgs with an empty package list:

Enter a frame number, or 0 to exit   

 1: depl_check("topics.Rmd")
 2: depl_check_run(lib_list)
 3: get_gh_data(install_candidates[!(install_candidates$package %in% CRAN_df$pa
 4: get_gh_pkgs(GH_install_candidates$package)
 5: purrr::map(package_list, ~get_gepuro_data(.)) %>% purrr::map(head, 1) %>% p
 6: withVisible(eval(quote(`_fseq`(`_lhs`)), env, env))
 7: eval(quote(`_fseq`(`_lhs`)), env, env)
 8: eval(quote(`_fseq`(`_lhs`)), env, env)
 9: `_fseq`(`_lhs`)
