...n, and wanted to provide helper methods in my model class. I was confused that the class DOESN''T refer to its fields as instance variables. I merely had to type in the field names to be able to work with their data. Here''s an example: I have a "Chessgame" class with a begindate and an enddate. To get the number of hours that the game took, I wrote an "hours" method in the Chessgame class. I thought that i would reference the begindate and enddate field as instance variables, but this did not work. I had to write the code like this: ------------------------...

hi all, I'm working on scrapping some website data to build a database. Under most cases, I can use package XML to get the dataset. However, some of the website doesn't give a explicit address of the downloaded tables. To be more specific, for example, I'm interested in the website http://ets.aeso.ca/ The data we are scraping is the "Pool Weekly Summary" under the

...e server. Has anyone else dealt with this sort of thing ? Does XP work reliably with Samba 3 as PDC ? * Why 2.2.5, well it's all down to support and integration. The whole system is supplied and installed as an integrated package - with Samba already set up to use the LDAP database that is begind the groupware stuff etc. The consultants setting all this up say that they have put Samba 3 in there for another customer without problems, but obviously it's not something Suse will support (yet, I guess it'll come during some future upgrade). I think it's a case of selecting pack...

...s between the start and end of the dives. But there is, I have checked. I reckoned that it has to do with the format of the datetime values. I couldnt find how to convert it to a numeric value. At the moment my datetime values are in a POSIXct format defined as follows as.POSIXct(strptime((dive$begindive),'%Y/%m/%d %H:%M:%S'),tz="GMT") I have also tried to sort the tdr data first in ascending order tdr <- tdr[order(tdr$datetime),] #sort z according to dtime I have even tried to convert to numeric format in excell (all three datetime values) and then use those numerics in R...
