similar to: POSIXct conversion stops part way through a df column

I have two data frames of flight data, but they have very different numbers of rows. They come from different sources, so the data are not identical. > names(oooi) [1] "FltOrigDt" "MkdCrrCd" [3] "MkdFltNbr" "DprtTrpnStnCd" [5] "ArrTrpnStnCd" "ActualOutLocalTimestamp"

Does anyone know why a data frame created with empty character columns converts them to integer columns? > df<-data.frame(a=character(0),b=character(0)) > df<-rbind(df,c("a","a")) > typeof(df[1,1]) [1] "integer" AsIs doesn't help: > df<-data.frame(a=I(character(0)),b=I(character(0))) > df<-rbind(df,I(c("a","a")))

How do I get a number representing a date from a POSIXct i.e. removing the time elements? -- View this message in context: http://n4.nabble.com/how-to-return-date-part-of-POSIXct-tp1598109p1598109.html Sent from the R help mailing list archive at Nabble.com.

Dear R users, I have a problem. I don't know how to select the top 10 (n) values for each classes. Thank you! My data is like this: row.names proc cls 7271 568,03338 0,5 7270 554,68458 0,5 7269 510,20638 0,5 7268 485,59969 0,5 7267 421,92852 0,5 7272 410,12101 0,5 3414 409,71429 0,5 3452 402,78699 0,5 3451 401,28114 0,5 3450 361,80607 0,5 3413 360,29883 0,5 3449 352,90043 0,5 3453

Hi, I am trying to simultaneously remove duplicate variables from two or more variables in a small R data.frame. I am trying to reproduce the SAS statements from a Proc Sort with Nodupkey for those familiar with SAS. Here's my example data : test <- read.csv("test.csv", sep=",", as.is=TRUE) > test date var1 var2 num1 num2 1 28/01/11 a 1 213 71 2

I am interested in studying the binary representation of numerics (doubles) in R, so am looking for possibilities of output of the internal binary representations. sprintf() with format "a" or "A" is halfway there: sprintf("%A",pi) # [1] "0X1.921FB54442D18P+1" but it is in hex. The following illustrate the sort of thing I want: 1.1001 0010 0001 1111

Hi all! I am using samba server at the company i work. Samba version is: 2:3.2.5-4lenny9 Some settings: os level = 255 domain logons = no wins support = yes domain master = yes local master = yes preferred master = yes i have dhcp configured witch sends wins server address (this samba servers address) to all clients. After I (re)start samba within a minute or so all computer of our network

Dear R-Help, With the attached data set, I am still getting incorrect bwplots > xyplot(gdf$tt~gdf$OnHour |gdf$Runway, data=gdf) # Is correct > bwplot(gdf$tt~gdf$OnHour |gdf$Runway, data=gdf, horizontal=FALSE) # Puts the boxes on the wrong x-axis values # look especially at 0 and 3. How do I fix this? What is happening? Thanks, Jim Rome

Dear list, I think I'm being dense, but I can't get combn or expand.grid to give me this result. I need to generate a matrix of all 16 possible sequences of 4 boolean elements, 0000 0001 0010 0011 0100 ..... 1111 (in the end I'll have to assign NA to the 0s and some value to the 1s but let's keep it simple) OK, I could go the following route, but I feel like reinventing the

I've created a dict service that listens on a unix socket and answers queries for sieve scripts (among other things). As I understand it (from the source code at http://hg.dovecot.org/dovecot-2.2/file/tip/src/lib-dict/dict-client.c), the dict client will unescape \001n, \001t, and \0011 to line feeds, tabs, and the \001 character respectively. In my service I am escaping those three

dear r users, i'm a little stuck with the following problem(s), hopefully somebody can offer some help: i have data organized in a binary matrix, which can become quite big like 60 rows x 10^5 columns (they represent SNP genotypes, for some background info). what i need to do is the following: let's suppose i have a matrix of size n x m. for each of the m columns, i want to know

How do I retain "POSIXct" formatting when using apply, with FUN=max? #example: mydata <- rep(Sys.time(), 10) mydf <- data.frame(matrix(data=mydata, nrow=2, ncol=length(mydata) ) ) for(i in seq(mydf))class(mydf[[i]]) <- class(mydata) str(mydf) maxdates <- apply(mydf,2,max,na.rm=T) str(maxdates) #Why is the formattign now "chr", and not

Hi, I know we've talked about this phone to death. I have pretty good voice quality, with and without WEP enabled, using the G729a codec and DLink & Netgear access points. I am facing one obstacle that is driving me insane. Does anyone have the call hold feature working? If you do... how did you make it work? The instructions say to press the left button to place the call on hold,

I was just reading the blog post -- very cool! Regarding Globals construction & destruction: There definitely has been a lot of churn in that area. There will probably be more before LLVM 11 is released, but I can see light at the end of the tunnel. I think the Right Way to run initializers in a JITDylib is to treat it as equivalent to a dlopen operation (with extra allowances for the fact

Due to a mistake I created a subdomain with the name of the domain itself. In my case the domain is briesebaer.intern and I created the subdomain briesebaer.intern. Using DNS RSAT Tool I see under briesebaer.intern the subdomain intern and then a recurrence of the whole domain. That means: under intern there is briesebaer and all of the dns query beneath. The query shows the Name=intern
