Reading Wyoming radiosonde data files with RadioSonde package
Hi, I need to do some analysis on historic daily radiosonde data I download from the Wyoming Univ. web page ( http://weather.uwyo.edu/upperair/sounding.html). I am trying to use the RadioSonde package (V 1.3), but the format of the files from Wyoming don't match what RadioSonde is expecting. Has anyone used the Radiosonde package on the Wyoming data? Here is a sample of the Wyoming file

importing NPDB
Does anyone have information about using the National Practitioner Data Bank (NPDB) in R? It's public use data available from the U.S. Department of Health and Human Services that can be downloaded as a .dat or .por file. I can't even figure out how to open the file in R.

NLS results different from Excel -- Tricky fortunes nomination
Folks: I thought the following excerpt from Bruce McCullough's post would be a good candidate for the R fortunes package -- except that it's about Excel, not R! So I nominate it... but leave it to others to say whether it's really "qualified" to be nominated. ---- "The idea that the Excel solver "has a good reputation for being fast and accurate" does not

need to delete by time, not date
I have a matrix where one column has a date and another column has a time. I need to delete all times before 6am. I had combined the Date and Time column into DateTime.

round up a number to 10^4
Hi all, I have a list of numbers, e.g., X = c(60593.23, 71631.17, 75320.1), and want to round them so the output is Y = c(60000, 80000, 80000). I tried Y<-round(X,-4), but it gives me Y = c(60000, 70000, 80000). Do anybody know how to round up a number to 10^4? Thank you in advance. Wendy -- View this message in context:

How to use as.Date (or something else) with "31-Jul-2010 23:59:00"
Hello I have a huge file (not an R-file) in which the first column is a string with date, hour, minutes and seconds (For instance, "31-Jul-2010 23:59:00"). I tried as.Date but the error msg was "Error in charToDate(x) : character string is not in a standard unambiguous format". I have checked the help for the function as well as date but to no avail.

GPS handling libraries or (String manipulation)
Dear all, I would like to ask you if R has a library that can work with different GPS formats For example  I have a string of this format N50° 47.513 E006° 03.985 and I would like to convert to GPS decimal format. that means for example converting the part N50° 47.513 to 50 + 47/60 + 513/3600. Is it possible to do that with R? What is the name of such a library? I would like to thank you in

Smoothing a path in 2D
Hello, I'm currently trying to find a method to interpolate or smooth data that represent a trajectory in space. For example, I have an ordered (=time) set of (x,y) tuples which constitute a path in a 2D space. Is there a way using R to interpolate between these points in a way similar to spline interpolation so that I get a smooth path in space? Greetings, Dieter -- Dieter Vanderelst

References verifying accuracy of R for basic statistical calculations and tests
Do you know of any references that verify the accuracy of R for basic statistical calculations and tests. The results of these studies should indicate that R results are the same as the results of other statistical packages to a certain number of decimal places on some benchmark calculations.

R for Windows 32-bit mode versus 64-bit mode
Hi All: We are developing (actually updating) a piece of code that runs in R. Due to some limitations of some the libraries we use, at the present time we would be limited to the 32-bit version of R on Windows. Does anyone have a feel (or even real knowledge) if most people these days run R on Windows in 32-bit or 64-bit mode? This would affect some development decisions. Thanks -Roy M.

Opinion on R plots: connecting X and Y
Attention R users, especially those that are experienced enough to be opinionated, I need your input. Consider the following simple plot: x <- rnorm(100) y <- rnorm(100) plot(x, y, bty='n') A colleague (and dreaded SAS user) commented that she thought that my plots could be "cleaned up" by connecting the X and Y axes. I know that I can do that with bty='l' but I

[O/T] undergrads and R
Dear R People: Are your undergraduate students receptive to learning R, as a rule? Most of the time, mine really like it. But this semester, they act as though they are being eaten by rats when learning R. They are not trying at all. Any similar experiences? If anyone has any good ideas, I would be THRILLED to hear them, as I am using R in Summer School. Thanks, Sincerely, Erin Hodgess
