I have to load 10 different data frames and then manipulate those 10 data frames but would like to do this in a more simplified code than what i am doing. I have tried a couple of approaches but cannot get it to work correctly. So the initial (bulky) code is: #Bin 1 #------- #Loads bin data frame from csv files with acres and TAZ data Bin1_main <-

What i thought was a simple process isnt working for me. After i create an multiple objects in a function (see below), how to i use those objects later in the program. I tried calling the function again and then the object i wanted and it worked the first time but now it doesnt( i think i defined the object outside the function accidently so then it worked but when run properly it doesnt). I

I have a dataframe imported from csv file below: Houseid,Personid,Tripid,taz 1,1,1,4 1,1,2,7 2,1,1,96 2,1,2,4 2,1,3,2 2,2,1,58 There are three groups identified based on the combination of first and second columns. How do I split this data frame? I tried aa <- split(inpfil, inpfil[,1:2]) but it has problems. Output desired is aa[1] Houseid,Personid,Tripid,taz 1,1,1,4 1,1,2,7 aa[2]

I have a procedure that goes sorts out some numbers based on specidifed criteria and for some reason the list contains double values in some of the rows such as: TAZs <- [[84]] [1] 638 [[85]] [1] 643 [[86]] [1] 644 732 [[87]] [1] 651 801 i would like to check list TAZs for double values and remove any if present. I have tried if (length(TAZDs==2)) rm(TAZDs[2]) but no luck. I cant

I am looking up a number based upon a randomly selected number and then proceed to the rest of my code if the corresponding value is greater than or equal to yet another value. so if Dev_Size = 14 and my randomly selected number is 102 and i am looking up 102 in the following table 100 21 101 4 102 9 103 52 104 29 So i select the the corresponding value of 102, which is 9 and

Good day all, I am having seom trouble building a simple vector. Below my sample code shows what ime trying to do and i have pointed out where the issue is. What happens not is that a single "TAZDetermine_FEET" is selected by i need multiple values, as many as there are "cands". I am thinking that this should occur within the for loop and add a

I am trying to simplify my code by adding a for loop that will load and compute a sequence of code 10 time. They way i run it now is that the same 8 lines of code are basically reproduced 10 times. I would like to replace the numeric value in the code (e.g. Bin1, Bin2....Bin10) each time the loop goes around. Below i tried doing this with a simple for loop and adding the string character before

Hello All, Please consider the following: TotEmp<-c(19,6,1,1,8,44,2,33,48,1) ClusterType<-c("AGF","CNS","OSV","RTL","RTL","TRN","REL","ACC_CLUST","RTL","WHL") Taz<-c(0,0,0,100,100,100,101,101,102,103)

Hello all, I have data from a csv that i need to coerce into a multi dimensional array. As you can see from my sample code i have yet to master building efficient code. I can sort of do what i want but its very cumbersome code and i know there is a better way to do it, i am just not expereinced enought yet. So for the following: #Create Data h1i1a1<-sample(1:20, 5, replace=TRUE)

I have consulted the intro and nabble but have not found an answer to what should be a simple question, here goes: I am doing a crosscheck of a data frame and pulling out a single value based on an inputted value ie based on x i will select y, or if x =2 then my code returns 7. x y 1 4 2 7 3 10 4 2 My code currently iterates through for as many times as the length of the x

To start off here is my version: drew@taz:~/downloads [14:26:56] -> wine -v Wine 20040505 When I run photoshop like this: wine "C:\\Program Files\\Adobe\\Photoshop 7.0\\Photoshop.exe" I get a little window form with an "OK" button that has "Adobe Photoshop 7.0" as it's title. I click OK, and it quits out. Any suggestions ? - Drew

Howdy y'all, I am looking to use the match function to match a data attribute to another data frame but i need it to do so on two criteria to ensure an appropriate match. The following matches incorrectly. I know the example looks pointless but its just an example. Perhaps there is another way of doing this? Thanks #Sample Data Props<-c("p754921","p754921"

Let's say I have a postfix box, named mail.thespider.com, which is setup to handle virtual mailbox domains. One of these domains will handle is, thespider.com, and my email address in that domain is boris at thespider.com. As I setup dovecot, I can telnet to the pop3 port (110) and test it by logging in as boris at thespider.com (I would try the imap port but I do not know how to login to imap

I am still searching for a solution to what i think is a simple problem i am having with building a vector in a for loop. I have built a more understandable example so hopefully that will help..help you, help me, if you know what i mean. dev=400 #test location model TAZs to reference cands=c(101,105,109) #Create Object of length of cands candslength=length(cands) #TEST TAZ Vector

Package: xenstore-utils Version: 4.0.1-2 all it says is: "Description: Xenstore utilities for Xen This package contains the Xenstore utilities." Wow, i never would have guessed that a package called xenstore-utils might contain Xenstore utilities. I'm glad that's cleared up! that just leaves a few tiny, niggling questions: 1. WTF are the Xenstore utilities? 2. What are

Dear all Off topic to some extent but Ted Harding has just called me to say he is (a) seeing large delays in the list messages when it is sent internally from hypatia.math.ethz.ch. I get only a delay of an hour which is reasonable in the scrap below but Ted reports delays of the order 24 hours, (b) messages he has sent to the list don't appear on it for a long time. Is anyone else

So i have a simple question that doesnt require sample code, not sure if that violates posting rules or not. Is this: [1] "111" "112" "113" "114" "115" "116" "118" "119" "120" "123" "125" "126" [13] "127" "128" "132" "137"

I am trying to build a R 1.7 package under Windows NT. I created the DESCRIPTION file, the RD file and added the code to the R folder. I also downloaded and installed the Rtools package and have Perl 5.0. I know that Perl, Miktex, and gcc are working. I also have my PATH variable set correctly. I can fake install my package by removing the *.R from the code file, using Rcmd Rdconv to create
