Regression Example: Error in current_env() : could not find function "current_env" #36

Closed alexhallam closed 6 years ago

alexhallam commented 6 years ago

I was going through the Regression Example. Below is my code.

#devtools::install_github("topepo/modelgenerics")
#devtools::install_github("topepo/parsnip", dependencies=TRUE)
#install.packages("AmesHousing")
#install.packages("rsample")
#devtools::install_github("imbs-hl/ranger")
#install.packages("rlang")

library(parsnip)
library(AmesHousing)
library(tidyverse)
library(rsample)
library(ranger)

ames <- make_ames()
set.seed(4595)
data_split <- initial_split(ames, strata = "Sale_Price", p = 0.75)

ames_train <- training(data_split)
ames_test  <- testing(data_split)

rf_defaults <- rand_forest(mode = "regression")
rf_defaults

preds <- c("Longitude", "Latitude", "Lot_Area", "Neighborhood", "Year_Sold")

rf_xy_fit <- rf_defaults %>%
  fit(
    x = ames_train[, preds],
    y = log10(ames_train$Sale_Price),
    engine = "ranger"
  )

I get the following error

Error in current_env() : could not find function "current_env"

I thought this was an rlang issue to I removed and reinstalled rlang. Then I thought is was a session issue so I restarted R, still no luck. I was wondering if you had any insight into this error.

If it is useful, this is the traceback.

The namespace file has import(rlang) so ¯_(ツ)_/¯

Can you install sessioninfo and run session_info() after the error?

topepo commented 6 years ago

It looks like you have to install the devel version of `rlang. That's odd since the DESCRIPTION file has

Remotes:
    tidyverse/rlang

using install_github should update things.

alexhallam commented 6 years ago

That fixed the problem! rlang must be installed via install_github

alexpghayes commented 6 years ago

Just ran into this despite an apparent rlang github install:

> remotes::install_github("topepo/parsnip")
Downloading GitHub repo topepo/parsnip@master
Downloading GitHub repo tidyverse/rlang@master
topepo commented 6 years ago

I downgraded rlang and ran devtools::install_github("topepo/parsnip"). I got me the right version of rlang. Between the remotes reference and and the dependency rlang (>= 0.2.0.9001) in DESCRIPTION, I ]m not sure what else to do.
