readNEWS {utils}R Documentation

Read R's NEWS file or a Similar One


Read R's NEWS file or a similarly formatted one. This is an experimental feature, new in R 2.4.0 and may change in several ways.


readNEWS(file = file.path(R.home(), "NEWS"), trace = FALSE,
         chop = c("first", "1", "par1", "keepAll"))


file the name of the file which the data are to be read from. Alternatively, file can be a connection, which will be opened if necessary, and can also be a complete URL. For more details, see the file argument of read.table.
trace logical indicating if the recursive reading should be traced, i.e., print what it is doing.
chop a character string specifying how the news entries should be “chopped”; chop = "keepAll" saves the full entries.


An (S3) object of class "newsTree"; effectively a list of lists which is a tree of NEWS entries.
Note that this is still experimental and may change in the future.


NEWStr  <- readNEWS(trace = TRUE)# chop = "first" ( = "first non-empty")
## keep the full NEWS entry text i.e. "no chopping":
NEWStrA <- readNEWS(chop = "keepAll")
object.size(NEWStrA) ## (no chopping) ==> about double the size

str(NEWStr, max = 3)

str(NEWStr[[c("2.3", "2.3.1")]], max=2, vec.len=1)

NEWStr [[c("2.3", "2.3.1", "NEW FEATURES")]]
NEWStrA[[c("2.4", "2.4.0", "NEW FEATURES")]]
