Hi, Being a novice this is my first usage of R. I am trying to use rpart for building a decision tree in R. And I have the following dataframe Outlook Temp Humidity Windy Class Sunny 75 70 Yes Play Sunny 80 90 Yes Don't Play Sunny 85 85 No Don't Play Sunny 72 95 No Don't Play Sunny 69 70 No Play Overcast 72 90 Yes Play Overcast 83 78 No Play Overcast 64 65 Yes Play Overcast 81 75

Newbie question, but I've checked archives etc. Am trying to reproduce in R Quinlan's trivial example of the "golf" decision tree. The data file of 14 examples follows (read in via read.table()): Outlook Temperature Humidity Windy PlayDontPlay 1 sunny 85 85 false DontPlay 2 sunny 80 90 true DontPlay 3 overcast 83 78 false Play 4 rain 70 96 false Play 5 rain 68 80 false Play 6

See ?rpart.control. I get: > golf.rp = rpart(Outlook ~ ., golf, control=rpart.control(minsplit=1)) > golf.rp n= 14 node), split, n, loss, yval, (yprob) * denotes terminal node 1) root 14 9 rain (0.2857143 0.3571429 0.3571429) 2) Temperature< 71.5 6 2 rain (0.1666667 0.6666667 0.1666667) 4) Temperature< 64.5 1 0 overcast (1.0000000 0.0000000 0.0000000) * 5)

Hi, I have seen that R has a implementation of decision trees; however, after I have the tree with the classification: R Quinlan's trivial example of the "golf" decision tree. Outlook Temperature Humidity Windy PlayDontPlay 1 sunny 85 85 false DontPlay 2 sunny 80 90 true DontPlay 3 overcast 83 78 false Play 4 rain 70 96 false Play ... What's next? I mean, what is this

When operating in daemon mode, will rsync check to see which file is newer and decide which direction to transfer based on that? Example, We have 2 terminal servers, A and B. I want users to be able to work on either server and have their home directories on both stay in sync. If a user logs into server A and changes files, the server would know to transfer the file from A to B. If they log

I ran into a problem that I couldn't resolve straight away, but would like to solve for sometime in the future. We have a Thecus storage server (similar to a Buffalo TeraByte, if that helps?) that has a Mac filesystem on it. The mother board was failing, but the drives are still OK. A new box has been added, so the urgency is sort of gone. I was going to try and back up the data to a new

Hi, The subject says it all. On my "server" machine in the local LAN (192.168.1.252 in a 192.168.1.0/24 network), I setup Bind. I installed the 'caching-nameserver' package, which provides a set of configuration files for Bind so it can be used as a caching nameserver out of the box. On the server : I start bind (service named start), and try it out. # host www.google.fr

Hi, I've just upgraded to Samba 1.9.17, but I can't get my samba server that resides in a differnet subnet to show up in the PDC's browse list.

Today I received an allocation of IP6 addresses for some servers. I can 'play' with the last 2 of the 8 IP6 address segments. I always thought, mistakenly, IP6 was 6 segments, because it was IP6. IP4 had 4 segments. However IP6 is actually IP version 6 and it has 8 segments. The other interesting discovers are: :: means one or more 0 segments, example :: can mean 0:0:0: or just 0:0: or

Hi everyone, I'm setting up a VPN over IPv6, attempting to build an IPv4-over-IPv6 tunnel, but when I try to connect to the server, I got this: System call `getaddrinfo' failed: Address family not supported. Client runs WindowsXP, and I did almost exactly the same as http://www.tinc-vpn.org/examples/windows-install . Here is the configuration files: ------- tinc.conf ------- Name =
