Hi, I have some confusion in applying a function over a column. Here's my function. I just need to shift non-March month-ends to March month-ends. Initially I tried seq.dates, but one cannot give a negative increment (decrement) here. return(as.Date(seq.dates(format(xdate,"%m/%d/%Y"),by="months",len=4)[4]) ) Hence this simple function: > mydate <-

Hi, Apologies for the long mail. I have a data.frame with columns of price/mcap data for a portfolio of stocks, and the date. To get the total value of the portfolio on a daily basis, I calculate rowSums of the data.frame. > set.seed(1) > ab <- matrix(round(runif(100)*100),nrow=20,ncol=5) > ab[1:5,4:5] <- NA > ab[6:10,5] <- NA > ac <- as.data.frame(ifelse(ab <=

Hi, A quick beginner's question. I have two time series, A with daily data, and another B with data at varying frequencies, but mostly annual. Both the series are sorted ascending. I need to merge these two series together in the following way: For any entry of A, the lookup should match with B until we find an entry of B that's larger than A's. For all A[i], i = 1,...,N and B[j],

Hi, Quick question: Say I have a date variable in a data frame or matrix, and I'd like to preserve the date format when using write.table. However, when I export the data, I get the generic number underlying the date, not the date per se, and a number such as 11323, 11324, etc are not meaningful in Excel. Is there any way I can preserve the format of a date on writing into a text-file? TIA

Hi, I have a history dataset, a matrix with about 1590 obs, and 242 cols, and I need to update this matrix with an 'update' matrix that has about 30 rows, and roughly similar number of columns as the history ds (but not necessarily equal). The update dataset is read from an Excel ODBC connection. When I try and merge these datasets, I get counter-intuitive results. library(RODBC) chn

Hi, Given a date, how do I get the last date of that month? I have data in the form YYYYMM, that I've read as a date using > x$Date <- as.Date(ISOdate(substr(x$YearEnd,1,4),substr(x$YearEnd,5,6),1)) But this gives the first day of the month. To get the last day of the month, I tried > as.Date(as.yearmon(x$Date,frac=0)) But I don't get the last day of the month here. (Tried

Can R invert a 160000x160000 matrix with all positive numbers? Thanks a lot!

I'm looking at scripting a mechanism to delete a mailbox, which is easy with 'doveadm mailbox delete' -- however it gets complicated when there are children of arbitrary depth, for example, I may have this: restored.daily1.INBOX restored.daily1.Sent restored.daily1.Mystuff restored.daily1.Mystuff.foo I would like to delete the 'restored' mailbox and all its children (and

Bill, Appreciate the point that both you and Serguei are making, but the sequence in question is not a selected or filtered set. These are values as observed in a sequence from a mechanism described below. The probabilities required to generate this exact sequence in the wild seem staggering to me.

Bill, I have clarified this on SO, and I will copy that clarification in here: "Sure, we tested them on other 8-digit numbers as well & we could not replicate. However, these are honest-to-goodness numbers generated by a non-adversarial system that has no conception of these numbers being used for anything other than a unique key for an entity -- these are not a specially constructed

Hi, There's no client activity and I have collected tcpdump for 5 mins on one of the glusterFs sever which is also a client with gluster NFS mount. From tcpdump I see that for every few seconds, STAT & STATFS commands are run. For whichctory are these commands being run and why?

Hi, I am trying to understand how the extended attribute trusted.io-stats-dump works. setfattr -n trusted.io-stats-dump -v /tmp/gluster_perf_stats/io-stats-pre.txt /mnt/gluster/gv0_glusterfs I can see that the io-stats-pre.txt is created. But how and what happened in the background? And why I can't I see the attribute with getfattr again? getfattr -dm- /mnt/gluster/gv0_glusterfs # file:

Hi, Can I get a brief description of all the FOPS in gluster or the location of the source code file so that I will try to get an understanding myself? Few FOPS I'm not clear like FORGET, UNLINK, FLUSH, LOOKUP Or is there a way I can tunnel through the FOPS that that are happening in the background for each operation? I have tried this to find from a brick logfile in TRACE mode, but there

Dear list members, Is there a package somewhere for jointly estimating two poisson processes? I think the closest I've come is using the "SUR" option in the Zelig package (see below), but when I try the "poisson" option instead of the "SUR" optioin I get an error (error given below, and indeed, reading the documentation of the Zelig package, I get the impression

Hi, Also I forgot to mention there are DUMP and PORTBYBRICK calls too. I understood these too calls are to get updated on gluster configuration. But all these two calls are to a particular node only while there are total (2+1)*3= 6 nodes in my configuration. Why so? What exactly is DUMP and PORTBYBRICK? Regards Jeevan.

Filtering the brick logs in TRACE mode with rpcsvc.c does show the FOPS. >From this, I've realized that LOOKUP is actually dns lookup. This actually differs from NFS lookup operation.

An ESTALE error usually means the gfid could not be found. Does repeating the "rm -rf" delete the directory?
