When I try to view a list of any decent size, RStudio just shows a blank screen, and after that, although I can enter commands in the console, nothing else can be executed.
The list comes from a group_by, nest(), regression analysis set-up shown below:
# Run regressions based on passed data
# `by_var` is NSE
# reg_formula must be passed from a `as.formula()` object
regress_by <- function(df, by_var, reg_formula) {
by_var <- enquo(by_var)
df %>%
group_by(!!by_var) %>%
nest() %>%
mutate(
lm_obj = map(data, ~lm(reg_formula, data = .x))
)
}
test <- regress_by(base, region, reg_form)
My guess is that RStudio chokes on the lm_obj part. Once I make the base data frame small enough RStudio will show test, but it still results in a sluggish experience. The screenshot shows the outcome when base is just shy of 3,000 observations and the regressions were done for 171 factors by region.
Once I make base much bigger than that, RStudio just hangs and I need to do a force quit.
On my system:
Chrome version RStudio/1.2.5042
Operating system Mac OS X 10.15.4
R 3.6.2
Update: I tried this on an RStudio Pro server that I have access (using R 3.6.3 and RStudio 1.2.5033-1) and I ended up crashing that one as well once the sample size became even moderately big (~30,000 observations).
