as.data.frame,es4dataframe-method | R Documentation |
i use this to quickly grab the underlying data.frame mainly in order to pass it cleanly to S3 methods, but there are other applications.
## S4 method for signature 'es4dataframe' as.data.frame( x, row.names = NULL, option = FALSE, ..., stringsAsFactors = FALSE )
x |
an es4dataframe |
row.names |
defaults to NULL |
option |
boolean defaults to FALSE |
... |
all the other good stuff |
stringsAsFactors |
boolean defaults to FALSE because why would you want to do anything else? note that this is not the default behavior of an as.data.frame method. |
a dataframe
es4dataframe
df1 <- data.frame(a = rnorm(10), b = rnorm(10)) dfx <- es4dataframe(df1) df2 <- as.data.frame(dfx) identical(df1, df2)
