I'm guessing there's a more efficient way to do the following using the index features of R. Appreciate any thoughts.... for (i in 1:nrow(dbs1)){ if(dbs1$Payor[i] %in% Payor.Group.Medicaid) dbs1$Payor.Group[i] = "Medicaid" if(dbs1$Payor[i] %in% Payor.Group.Medicare) dbs1$Payor.Group[i] = "Medicare" if(dbs1$Payor[i] %in% Payor.Group.Commercial)

I have beautiful box and whisker charts formatted with lattice, which is obviously calculating summary statistics internally in order to draw the charts. Is there a way to dump the associated summary tables that are being used to generate the charts? Realize I could use tapply or such to get something similar, but I have all the groupings and such already configured to generate the charts. Simply

I'm migrating our mailserver from cyrus 2.0 to Postfix and Dovecot. We're using maildirs delivered to /var/maildir, which is mounted via NFS from a Netapp. My understanding was that maildir was completely happy in an NFS environment but I've seen a couple messages here recently which mention the dovecot index files not being NFS safe. Are their any caveats or gotcha's that I

Have a long script that runs fine on windows (32 bit). When I try to run in on two different macs (64 bit), however, it hangs with identical behavior. I start with: library(sqldf) This results in messages: Loading required package: DBI Loading required package: RSQLite Loading required package: RSQLite.extfuns Loading required package: gsubfn Loading required package: proto Loading required

Hi there, hope I can explain this one! When I try to use a setStyle call and set the backgroundImage property of an element, I''m having some problems using a relative URL. my directory structure is this: SERVER_ROOT/context/javascript/tree.js SERVER_ROOT/context/style/tree/tree.css SERVER_ROOT/context/images/node_icons/open.png SERVER_ROOT/context/images/node_icons/closed.png in my

Know that if I have List_1 and List_2 that I can check to see if the intersect via the code below: List _1: a, b, c, d, e, f, g List_2: z, y, x, w, v, u, b length(intersect(List_1, List_2)) > 0 return = true If instead I wanted to check a dataframe that is a "list of lists," how would I do that by record without looping? List _1: a, b, c, d, e, f, g List_2: z, y, x, w, v,

I am using the code below to extract census tract information. save.tract$state, save.tract$county and save.tract$tract are returned as factors. In the last three statements, I need to save the actual value of the factor, but, instead, the code is yielding the position of the factor. How do I instead return the value of the factor? By way of example, for Lon=-82.49574 and Lat=29.71495, the code

trying to structure sql to merge two datasets. structure follows: dbs.possible.combos (all possible combinations of dates and places) Date Place 1/1/10 N-01 1/1/10 S-02 1/2/10 N-01 1/2/10 S-02 etc... dbs.aggregate (the raw data aggregated by date and location) Date Place Days 1/1/10 N-01 6 1/1/10 S-02 10 1/2/10 S-02 5 Trying to merge so I look-up the values for each possible combo dbs.final

If I have a column with 2 levels, but one level has no remaining observations. Can I remove the level? Had intended to do it as listed below, but soon realized that even though there are no observations, the level is still there. For instance summary(dbs3.train.sans.influential.obs$HAC) yields 0 ,1 4685,0 nlevels(dbs3.train.sans.influential.obs$HAC) yields [1] 2 drop.list <- NULL

Hello, I''m trying to create a HVM virtual machine (windows guest) with 3G of memory but this isn''t working. Xen create the domain but nothing happens (the OS don''t start and the cpu time remains 0). Things start to work with 2000MB or below. Is there some kind of upper limit for HVM virtual machines? I''m using a Dell PowerEdge 8250 machine with 16GB of memory.

Have a simple bwplot with 24 ordered factors across the x axis. I would like to only label every 4th tick mark so that the labels fit. I tried scales=list(x=list(tick.number=6)), but I still seem to get 24 tickmarks and 24 labels. Full code is below: bwplot(SumOfIn.Use ~ Hour | Period, scales=list(x=list(tick.number=6)),horizontal=FALSE,las=2,main="Rooms Running",sub="Timeframe:

When I run sqldf to merge two datasets, it's changing the Date (class date) to a numeric value (class factor). Not sure why. Appreciate any insight.

Dataframe1 contains a list of specific dates. Dataframe2 contains a large dataset, one element of which is Date. How do I create a subset of Dataframe2 that excludes the dates from Dataframe1? I know how to do it with a left outer join vs null in SQL, but I can't figure out how to do it more directly via the subcripts that already exist? Dateframe1 Date 1/1/2010 1/18/2010 Dataframe2 Date

I need to merge three datasets and don't know how. If I were using SQL, I would use df3, look up the characteristics of each date in df1 and the value for each observation in df2. df1 - unique list of Dates and characteristics of those dates Date, YYYYMM, YYYYWW, DOW df2 - the raw data Date, Place, Value df3 - all posibile combinations of Date + Place (via
