Save investigation info

hugo_save_investigation saves variables and packages used in investigation. Data is stored in subfolder 'resources/session_name' in two separate files: _variables_ and _packages_ Written data can be read back at later date by using function _hugo_continue_investigation_.

hugo_save_investigation(variables = NULL, session_name = NULL,
  envir = .GlobalEnv)

Arguments

variables	a character vector containing names of important variables to be saved. By default _variables = NULL_, then all the variables in environment _envir_ are saved.
session_name	name of directory in which the session will be saved. If session_name = NULL, the dafault name is set.
envir	an environment to search for objects to be saved. Global Environment by default.

Examples

# NOT RUN {
hugo_start_investigation("Example")
model <- lm(Petal.Width~., data = iris)
res <- model$residuals
petal.pred <- predict(model, newdata = iris)
hugo_save_investigation()
# or select variables to be written out and set name of session's directory:
hugo_save_investigation( variables = c('petal.pred', 'res'), session_name = 'IrisModel')
# or select the environment that contains variables for saving
e <- new.env()
e$a <- FALSE
e$b <- "a"
expect_output(hugo_save_investigation(envir = e))
# }
