Hi, In short, I would like to know if there is any way to convert a numeric into a date, similar to how strptime() can convert a string to a date time class? There are some functions, etc. which don't work well with dates, and tend to force them into numerics. I understand that the number it spits back is the number of seconds since the beginning of 1970 (see the first few sentences

Hey everyone, I know that I can call 'R' from other scripts, and that I can make command calls from 'R' (e.g., using system() ). But how can I get 'R' to RETURN values to the script that called it. E.g., I would like to be able to do something like the following (as a simpler example) from a bash script: #!/bin/bash myTest=echo /usr/local/bin/R --no-restore

This question might seem silly, because I felt that it MUST be in the mailing list archives or help files somewhere, but I simply couldn't find it. I want to make some simple CDF (cumulative distribution function) plots to check whether distributions are Gaussian / normal. But in order to check how "normal" the distribution is, I really need the y-axis to be Gaussian as well

...e is curious, let me know & I can supply the code. Thanks!

Hey everyone, I've been using 'R' long enough that I should have some idea of what the heck either expression() or eval() are really ever useful for. I come across another instance where I WISH they would be useful, but I cannot get them to work. Here is the crux of what I would like to do: presume df looks like this A B C === === === M 45 0 M

oh, I am using: $ quota -V Quota utilities version 3.13. Compiled with RPC and EXT2_DIRECT Bugs to mvw at planets.elm.net, jack at suse.cz are there any special versions out there for v2 quotas? thanks, Christian. ------------- Hi list, having used ext2/3 for years now I have to admit that I've never dealt with filesystem quotas yet. But now I want to use them and I'm rather puzzled that...

Hi Everyone, I did a search through the archives and did not find an answer, although I must admit it is a hard search to do ( ^0.5 is tough to explicitly search for ). I am sure there is some mathematically accurate reason to explain the following, but I guess I either never learned it or have since forgotten it. In 'R', when I type (for instance): sqrt(-4) I get NaN

Hello, I have a (relatively long) function script that generates a levelplot. I don't want to include all of the code, so I have attached in file "miniDataSet.csv" an example for the data set "miniDataSet" that is called below. The function works OK, except that when the variables in the "splitCol" column get very large (as they are in this data set I

Hello all, First of all, thanks so those of you who helped me a week or so ago managing a time series with varying gaps between the data series in 'R'. (My final preferred solution was to use "its" function & then forecast(Arima( ) ). ) My next question is a general statistical question where I'd like some advice, for those willing / able to proffer any wisdom:

Hi all, I am using the package "random forest" for random forest predictions. I like the package. However, I have fairly large data sets, and it can often take *hours* just to go through the "na.roughfix" call, which simply goes through and cleans up any NA values to either the median (numerical data) or the most frequent occurrence (factors). I am going to start

Hello, This is mostly to developers, but in case I missed something in my literature search, I am sending this to the broader audience. - Are there any plans in the works to make "time" classes a bit more friendly to the rest of the "R" world? I am not suggesting to allow for fancy functions to manipulate times, per se, or to figure out how to properly

Hi All, First let me state that I did search for a while on r-help, google, and using the "sos" package inside of 'R', without much luck. I want to know how to create a univariate time series from a set of data that will have huge time gaps in it. For instance, here is a snapshot of a piece of data that I would like to analyze: *Row queued_time

Hi All, I don't have a "I need help" question, so much as a query into any update whether 'R' has made any progress with some of the core functions retaining classes. As an example, because it's one of the cases that most egregiously impacts me & my work and keeps pushing me away from 'R' and into other numerical languages (such as NumPy in python), I

Hello all and thanks in advance for any help, There are really two issues that I am having, both related to saving graphs: 1) It seems that the "dev...()" functions are unstable when using higher level graphs (specifically I was using levelplot) 2) I have a large grid of levelplot graphs that I can print out into a subset quite easily when I print to screen, but if I print to a
