Since there has been a recent tweak to the functionality of Sys.setFileTime() I thought it might be an opportune time to ask a question regarding the decision to set both access and modification times (i.e. settime.actime = settime.modtime = (int)ftime; ) vs provide a parameter for each. Might it be possible to change the behavior to accept two parameters (one for active and one for modtime) but

Thanks for the link.? Somehow the information about how to join the bugzilla site was not available at bugzilla and buried in the CRAN web site instructions on reporting bugs (which pointed me at Bugzilla and not the page you showed me). The example is pretty minimal.? I left the tracing statements (flog.trace()) and the toJSON, fromJSON in as I thought they might provide some context for

I'm trying to implement a connection between two processes using a simple socket mechanism. The messages are rather long object stored as JSON. R is crashing with a segmentation fault when I try to read my test message (which is 5305 bytes long). I first send the length in bytes and then I send the actual message. Here is my R code: library(jsonlite) library(futile.logger)

I have spent hours on R in Windows 7. Just installed 2 days ago so the R package should be current. Currently I am using the RGui (64-bit) for Windows. I can not read an Excel file into R from my computer. Have hours on this. Completely crazy!! I have the XLConnect package loaded. I think it is loaded because when I enter: > loadedNamespaces() [1] "base"

Hi Folks, If you need to send data from Java to R you may consider using the JDataFrame API -- which is used to convert data into JSON which then can be converted into a data frame in R. Here's the project page: https://coherentlogic.com/middleware-development/jdataframe/ and here's a partial example which demonstrates what the API looks like: String result = new JDataFrameBuilder()

I have been using aggregate function to determine the annual minimum in a daily time series. However, I was also hoping to determine the date of occurrence without having to loop through each year to identify the date of each minimum returned from aggregate(). Is there a more convenient way of doing so? Thanks in advance, Dave library(zoo) n <- 1000 dly <- zoo( x = rnorm(n), order.by

I am trying to pass the result from a javascript function along with the result from a text_field with form_remote_tag.

But my question is more complicated than that one. In my case, log(E(y)) = s(x) where y is a smooth function of x. What I want is the confidence interval of a ratio of log[(E(y2))/E(y1)] given two fixed x values of

The person on the other side hears a perfect call, but the SIPphone side gets to hear themselves. It happens 100% of the time to some numbers (outgoing only), and only sporadically to others. Has anyone

I am planning on using Runt to calculate recurring events. I calculate a Runt object in the view and use it to see if it includes a certain date, which is populates from the database, and display the info for that date if it is included. I have recurring events for every week, which was pretty easy to set up. I can just say: r = Runt::DIWeek.new(4) For a recurring event every Thursday, and

I have been using SMS_fu but it seems too good to be true for production. I''m wondering, is there any sort of limit on email to sms depending on the carrier that you can send in a given amount of time? I remember reading somewhere that there is a limit to the number of free email to sms that you can send through AT&T in a given month. Does anyone know anything aobut this? I guess I
