slplot issue
In a prior life I was able to use slplot can change the xlim and ylim such that the ellipse was a perfect circle. It seems that the xlim and ylim are no longer supported by the slplot function. Any thoughts on how I can change this? Thank you kindly, -------------------------------------------------------------- Shawn Way, PE MECO, Inc. (p) 281-276-7612 (f) 281-313-0248 <img

[PATCH 4/4] vbios/prom: fetch the vbios using only aligned 32-bit accesses
Other kind of accesses are unreliable on Maxwell cards. As advised by NVIDIA, let's only use 32-bit accesses to fetch the vbios from PROM. This fixes vbios fetching on my nve7 which failed in certain specific conditions. I suggest we Cc stable, for all kernels they still maintain after the big rewrite.

efficient code - yet another question
Dear list members; The code given below corresponds to the PCA-NIPALS (principal component analysis) algorithm adapted from the nipals function in the package chemometrics. The reason for using NIPALS instead of SVD is the ability of this algorithm to handle missing values, but that's a different story. I've been trying to find a way to improve (if possible) the efficiency of the code,

S4 classes, some help with the basics
Hi All, I have tried to find an answer within documentation, but I cannot: o How can call a class "slot" without knowing the name a priori? E.g., let's say I use the "pcaMethods" library to create a "pcaRes" object. How can I call parts of that object without using the specific names of the object in the call? example code: library(pcaMethods)

Plotting cumsum data using lattice plots according to date conditioned by name.
I've been playing around with data like the following: Name Date Hrs Way, S 2-3-12 8 Nun, B 2-3-12 9 Way, S 2-4-12 7.5 Nun, B 2-4-12 9 Gus, T 2-5-12 8 I've been able to take this into a data.frame and even develop a cumsum for each of the people d.cum <- with(data,by(Hrs, INDICES=list(date=as.POSIXct(Name)),FUN=cumsum)) This gives me a list personnel with an array

Principal Components for matrices with NA
Hello, I have a matrix with 267 columns, all rows of which have at least one column missing (NA). All three methods i've tried (pcs, princomp, and prcomp) fail with either "Error in svd(zsmall) : infinite or missing values in 'x'" (latter two) or "Error in cov.wt(z) : 'x' must contain finite values only" The last one happens because of the check if

Evaluation failure of IAPWS95 functions in a rowwise manner (tidyverse style)
Hi Shawn, I don't think it has anything to do with the tidyverse.

PCA
Hi, I'm trying to perform a Principal Component Analysis on meteorological data with 10 predictors. I use the library pcaMethods to obtain a lot of information (loadings, scores, mean, standard deviation, etc). How can I obtain the scores (new PC variables) for new values of weather predictors using the results of PCA analysis (loadings, mean value, standard deviation) and without

RSpec and RCov with JRuby
Hi, I am using JRuby (trunk) and wrote a bunch of specifications for my code. Everything works fine so far. Now I am trying to integrate RCov in my test run. I have installed RCov without the C extensions. I tried it with a simple script and it worked (pretty slow, but it doesn?t matter). But when I add the rcov options to my Rake task, RCov is not invoke properly! Rakefile:

apply function across two variables by mult factors
Greetings, I am attempting to run a function, which produces a vector and requires two input variables, across two nested factor levels. I can do this using by(X, list(factor1, factor2), function), however I haven't found a simple way to extract the list output into an organized vector form. I can do this using nested loops but it isn't exactly an optimal approach. Thank you
