Hi r-help forum, I have been collecting contact data (with proximity logger collars) between a few different species of animal. All animals wear the collars, and any contact between the animals should be detected and recorded by both collars. However, this isn't always the case and more contacts may be recorded on one collar of the two. This is fine, it depends on battery life and other

Hi I'm trying to measure the effect of a policy intervention (Box and Tiao, 1975). This query has to do with the coding of the model rather than with the particulars of my dataset, so I'm not providing the actual dataset (or a simulated one) in this case, apart from some general description. The time series are of length n=34 (annual observations between 1977 and 2010). The policy

I have a data frame with 1 factor, one date, and 37 numeric values: str(waterchem) 'data.frame': 3525 obs. of 39 variables: site : Factor w/ 64 levels "D-1","D-2","D-3",..: 1 1 1 1 1 ... $ sampdate : Date, format: "2007-12-12" "2008-03-15" ... $ CO3 : num 1 1 6.7 1 1 1 1 1 1 1 ... $ HCO3 : num 231 228 118 246

Hi R help forum, I have a simple data frame of four columns - one of numbers (really a categorical variable), one of dates and one of data. I have over 500,000 data points to work with, spread over 40 files, each named after a different animal. These are contact data recorded by proximity loggers over two years between the animals of the file name and collars being worn by other animals. The

Howdy, R Grues I have enjoyed R, but I cannot solve one problem easily. Please help my problem. When I tried the R script, I got the following Error. This error results from input data file exported through a Excel spreadsheet software. Error in step(lm(pop.rate ~ as.numeric(year) + as.factor(policy) + as.numeric(nation.grant) + ?: ??number of rows in use has changed: remove missing values?

Hi LLVMDev, this is Jeehoon Kang, a Ph.D. student of Software Foundations Laboratory ( http://sf.snu.ac.kr), Dept. of Computer Science & Engineering, Seoul National University. Our group studied the mem2reg pass, and we got a question on its algorithm. As far as I understand, the mem2reg pass essentially uses the SSA construction algorithm to promote allocas into registers, but there are

Hello, My name is Chung Hae Young, and I work for NCsoft in Seoul, Korea. I am currently working on a online game development project. I have some questions regarding Ogg Vorbis. I want to change the library source and change Ogg game music files so the file can only be played within the game. I want to know if I can modify the library. And if I modify it, will if cause any legal

If uninitialized, char variable has indeterminate value, and C/C++ does not seem to forbid reading trap

Hello Fedor. Thank you for the information. I made a simple patch that exposes PassInstrumentationCallback so llvmGetPassPluginInfo can use it: https://reviews.llvm.org/D71086 .

I think we need to allow this.  Otherwise, we have to prove that addresses are non-undef before we can hoist or sink a memory instruction.  Today, aliasing can use things like known bits, and if we imposed a no-undef in address requirement, we'd either need to replace such reasoning in AA, or have passes which wish to hoist/sink check the property afterwards. Or to say it differently, I
