Re: [Rd] read.table / type.convert with NA values

Is there a compelling reason to have strip.white default to FALSE? It seems to me that it would be more common to want the TRUE case. Having said that, I must confess that I've never had the problem Erik describes. -Peter Ehlers On 2010-06-29 17:14, Matt Shotwell wrote: The document RFC 4180

Re: [Rd] read.table / type.convert with NA values

The document RFC 4180 (which appears to be the CSV standard used by R, see ?read.table) considers spaces to be part of the fielded value.

[Rd] Documenting non-exported objects

2010-06-29 Thread Hadley Wickham

[Rd] POSIXlt matching bug

2010-06-29 Thread McGehee, Robert
I came across the below mis-feature/bug using match with POSIXlt objects (from strptime) in R 2.11.1 (though this appears to be an old issue). > x <- as.POSIXlt(Sys.Date()) > table <- as.POSIXlt(Sys.Date()+0:5) > length(x) [1] 1 > x %in% table # I expect TRUE [1] FALSE FALSE FALSE FALSE FALSE FAL
