We recently started upgrading users' workstations to CentOS6. Now we've come across an interesting issue: ~user/.local/share/gvfs-metadata is filling up with tons of files. Once there are around 69270 of them, no more are being created, and the NetApp filer the user's home is on logs: Directory ..../user/.local/share/gvfs-metadata/ reached the maxdirsize limit.

Hi, Please can you tell me what I am doing wrong. When trying to merge two xts objects, one of which has multiple character vectors for columns...I am just getting NAs. > str(t) POSIXct[1:1], format: "2011-01-04 11:45:37" > y2 = xts(matrix(c(letters[1:10]),5), order.by=as.POSIXct(c(t + 1:5))) > names(y2) = c(1,2) > y2 1 2 2011-01-04 11:45:38

I see that "xl list" shows a domain waiting idly for console input as "r", whereas "xm list" shows the same domain as "b". I also see that the State field for "xl list" contains only three characters (e.g. "r--"), whereas "xm list" shows six (e.g. "-b----"). Is this expected/intended (e.g. "r" in xm list

Hi, I have a very large XTS object. It is about 600,000 entries over 1 year time. I would like to subset a specific piece, by "number of days" not a specific date. The way I do it now is awkward. Would love to find a way to do this easier to generate a new object just containing the days I want. --------------------------------------- dayEnds <- endpoints(dataset,

Is there a easy way to create the time index for a zoo/xts object for every 100 milliseconds. eg. time Index would be: 10:00:00:100 10:00:00:200 10:00:00:300 10:00:00:400 I am looking to build an empty zoo/xts object with time index from 10am to 3pm, index jumps by 100ms each row.

Hi everyone: I did a search over the internet and still couldn't find answer to my problem.

Hello, I coming across a strange problem doing math on an xts object. If I have an xts object of stock prices (perhaps 5 minute bars of open, high, low,close) and want to do some math, the results fail. For example: d$close[10] - d$open[10] works perfectly d$close[10] - d$open[9] fails. I just get an answer of "numeric(0) Index: numeric(0)". My guess is that xts is breaking

I have a data.frame object and I don't really understand how to made an xts class out of it.

I would like to add vertical shaded blocks in plot.xts graphs (like recession periods in FRED graphs) The reason I use plot.xts instead of plot.zoo is that I like the fact that the grid is automatically aligned with major ticks in plot.xts. xblocks() and rect() do not seem to work with plot.xts (only with plot.zoo). Are there any alternative methods that work with plot.xts? Thanks. -- View

Hi to all, i'm new to R I have an xts object. Can i find: a) how many NA are in my object ? b) eventually where (in which line) they are Thank you

Hi, I am trying to install package xts. I am using OPENSUSE 11 64 bit. When I invoke: install.pacakges("xts",dependencies=T) I received a lot of "ERROR: compilation failed for package" errors when R tries to install xts dependencies. I do not understand this behavior. I notice one thing. It complains. ERROR: compilation failed for package 'Hmisc' ** Removing

So I've got a 154 column wide xts time series object and I want to plot the 154 series on a single plot and have the added benefit of the time series dates on the x axis. Any suggestions for plotting functions, maplot works but does not give dates on the axis and I can't seem to get plot to give me more than one series. Nick [[alternative HTML version deleted]]

dear r folks i am a bit puzzled about how to use chron as an index xts and why it differs from zoo. in this example, why can i index zoo but not xts x<-1:23 time.of.day <- times(paste(x,":0:0",sep=""),format="h:m:s") day <- dates("4/8/90") period <- chron(dates=day,times=time.of.day) xts(1:23,period) zoo(1:23,period) i suspect it might be to

Dear R People: This is probably is very simple question. I have a monthly time series, ibm$ts , that I would like to convert to a quarterly series.

Hi, I am trying to add a vertical arrow (from top to bottom or from bottom to up) to a time series plot using ggplot2 and xts. It seems that the vertical line command "geom_vline" does not work for this purpose (Correct me if I am wrong). I try the command "geom_segment" as follows, but I got an error message at the last line "Error: Invalid input: date_trans works
