I am having difficulty understanding how I would constrain a data set by filtering out 'records' based on certain criteria. Using SQL I could query using 'select * from my.data where LithClass in ('sand', 'clay')' or some such. Using subset, there seem to be ghosts left behind (that is, all of the LithClass *.Labels* remain after subset) > dput(tcc)

R folks, As an R novice, I struggle with the mystery of subsetting. Textbook and online examples of this seem quite straightforward yet I cannot get my mind around it. For practice, I'm using the code in MASS Ch. 6, "whiteside data" to analyze a different data set with similar variables and structure. Here is my data frame: ###subset one of three cases for the variable

Hello all   I have a geology map that has three level, bellow   <-geology lithology    landscape   landform     landform level is used as covariate (with codes=1,2,3,4,5) for training of neural network, but this level has missing data as NA. I want to replace the missing data of landform level with 0 (zero). Finally, landform will have codes  0,1,2,3,4,5.   please help me   Thanks alot.

Hi all, This is more a help on ideas that on actuall R code. Those of you which are geologist or work with boreholes woudl understand that i would like to achieve. I'll tr to explain as good as I can...so here it goes.. I have around 1000 geomechanical (geological) borehole logs in a database. The logs contain staial info, lithology and some laboratory data. My initial goal is

Hi all I want to construct a generalised nonlinear model (binomial family) using gnm, of the form: Response = a + b variable1 + c variable2 + d variable3 - d b variable4 - d c variable5, with the parameters b, c, and d appearing more than once. Hence, I think I need to use a custom nonlin function with gnm. One of my predictor variables is categorical, so I have created a dummy variable for

For an axis label I want to include the Greek letter mu within the string. I've not found the proper way of including that expression within the string. What I want is "Conductivity (uS/cm)" with the 'u' replaced by mu. When I try "Conductivity (" expression(paste(mu)) "S/cm)" I get an error. If I don't separate Conductivity and S/cm with

hello mailing list! i still consider myself an R beginner, so please bear with me if my questions seems strange. i'm in the field of biology, and have done consecutive hydraulic conductivity measurements in three parallels ("Sample"), resulting in three sets of conductivity values ("PLC" for percent loss of conductivity, relative to 100%) at multiple pressures

The data is of two forms, ie one numeric and another ordinal ie 1.5 and <.5. The X Value is a factor. I'm trying to create a lattice conditioned plot with the following characteristics: 1) The plot is conditioned using the form (Conductivity~Day|Valve) 2) The plot should use a barplot for the ordinal (<.5) and dots for the numeric (1.5) 3) A line should be created specifying a

The last line of the example in droplevels' manual page seems to be incorrect to me. I think it should read: "table(droplevels(aq$Month))". Amazingly (I don't understand) both variants seem to produce the same result (R 3.3.3): --- > aq <- transform(airquality, Month = factor(Month, labels = month.abb[5:9])) > aq <- subset(aq, Month != "Jul") >

The behaviour of within() with list input changes if you delete 2 or more variables, compared to deleting one: l <- list(x=1, y=2, z=3) within(l, { rm(z) }) #$x #[1] 1 # #$y #[1] 2 within(l, { rm(y) rm(z) }) #$x #[1] 1 # #$y #NULL # #$z #NULL When 2 or more variables are deleted, the list entries are instead set to NULL. Is this intended?

Rainer, Arjen I was wandering around the code, and found that few things are missing around the IVT code: - no manpage, - no entry in driver.list - no device{mfr,model,type} in the code. I was about to submit a patch to address the above (ready to commit), but wanted first to get an update on the status. looking at the last thread, it's a bit unclear... I'm also interested an upsc

I figured out my previous problem with DIBuilder. However, now I can't seem to get the compiler to emit location information for local variables. Here's how my IR looks: --- define i32 @"\01_main"() { init: %exception1 = alloca i8* %0 = alloca i32 %"bar:Int32" = alloca i32 %1 = alloca i32 %2 = alloca i32* br label %code code:

This patch makes "xm info" show information on xen version, compile info, number of socket/core, etc... In order to do that, it extends physinfo hypercall to return number of socket, adds few functions to libxc and extends python wrapper correspondingly. Here is the output of new "xm info": -- system : Linux host : ubuntu xen_release

Dear R users, has anybody made an attempt to create the soil texture triangle graph in R? For an example see here: http://www.teachingkate.org/images/soiltria.gif I would like to get the lines in black and texture labels in gray to allow for plotting my texture results on top. Any examples or suggestions are very welcome! Thanks in advance, Sander. --

I found the problem. The llvm.dbg.declare call must have a !dbg tag, otherwise the location info is not generated. Changing the invocation in my original example to "call void @llvm.dbg.declare(metadata !{i32* %"bar:Int32"}, metadata !13), !dbg !16" causes MC to generate the local location as expected. -Joe On Thu, Dec 29, 2011 at 12:41 PM, Joe Groff <arcata at

Hi I have two irregular time series, which are of different lengths and being and end at different times. For the common subset of time that they both span, they should have the same values, but the values may occur at slightly different time intervals. I am trying to "line up" the identical values and reconcile them. I have merged the two series into a zoo object which looks
