make_df: Turn objects into data frames
In renlund/dataman: Data management

Description Usage Arguments Author(s) Examples

Some R functionality (I'm thinking mainly of ggplot2) requires the data you are interested in to be packaged in data frames, hence this function.

1	make_df(object, env, ...)

`object`	an object
`env`	an environment
`...`	passed arguments

Henrik Renlund

# combine variables into a data frame
x <- 1:2
y <- letters[1:2]
make_df(c("x","y"))
# 'env' is R_GlobalEnv by default but can be any environment, data frame or list
make_df(c("mpg", "disp"), env=datasets::mtcars)
# methods include 'list' ...
make_df(list(x=1:2, y=letters[1:2]))
# and 'survfit'
if(FALSE){
  n <- 50
  s <- survival::Surv(rexp(n), rbinom(n,1,0.2))
  f <- factor(rep(letters[1:2], length.out=n))
  sf <- survival::survfit(s~f)
  make_df(sf)
}
