I am having problems using merge with all = TRUE when one of the dataframes has objects of class POSIXct. Here is an example:
version
_ platform sparc-sun-solaris2.6 arch sparc os solaris2.6 system sparc, solaris2.6 status major 1 minor 3.0 year 2001 month 06 day 22 language R
x <- data.frame(a = as.POSIXct(Sys.time() + (1:3)*10000), b = LETTERS[1:3]) x
a b 1 2001-10-04 17:37:46 A 2 2001-10-04 20:24:26 B 3 2001-10-04 23:11:06 C
y <- data.frame(b = LETTERS[3:4], c = 1:2) y
b c 1 C 1 2 D 2
merge(x, y)
b a c 1 C 2001-10-04 23:11:06 1 # This answer is correct
merge(x, y, all = TRUE)
Error in as.POSIXct.default(value) : Don't know how to convert `value' to class "POSIXct" -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-devel mailing list -- Read http://www.ci.tuwien.ac.at/~hornik/R/R-FAQ.html Send "info", "help", or "[un]subscribe" (in the "body", not the subject !)
