[R] for loop if else conditional

[Vishal Belsare]

date <- as.POSIXlt(Sys.time())                  #present date

for (i in 1:difftime(as.POSIXlt(Sys.Date()),"2007-10-01"))
if (date$wday != 0 & date$wday != 6)
{print(date);assign("date", (date-86400))} else (assign("date", (date-86400)))


I am trying to print dates from present day to a day in the past, but
omitting weekends. I am not doing something right, but can't figure
out what. Help appreciated!
