Dear R users, I want to aggregate all *d *data from all combination of n *plots* taken by k. Thank very much! My data is like that: plot d 1 14 1 13 1 12 1 14 1 18 1 20 1 21 1 43 1 108 1 43 2 41 2 61 2 83 2 61 2 84 2 45 2 21 2 12 2 11 ... 100 10 100 12 -- --- Catalin-Constantin ROIBU Forestry engineer, PhD Forestry Faculty of Suceava

I have a problem about reading data into R. There is a "\n" between each pair of data, like: -155.65 -155.77 -155.40 -155.46 -155.52 -155.34 ... Could anyone tell me how to read in such data? Thanks! Rui

Short question: Is it possible to use statistical tests, like the Augmented Dickey-Fuller test, in functions with for-loops? If not, are there any alternative ways to scale measures? Detailed explanation: I am working with time-series, and I want to flag curves that are not stationary and which display pulses, trends, or level shifts. >df DATE ID VALUE2012-03-06 1

...alues to be normalized between 0 and 1 by column. Therefor, the 0 should correspond to the minimum value in the column c1 and 1 should correspond to the maximum value in the column c1. The remaining columns should be organized in the same way. Does a function in R exists for this purpose? Thanks, Rui [[alternative HTML version deleted]]

Hi, I have a small problem with the function split() and would appreciate your help. I have a table called ?XXX? with 2 columns and 49 rows. The 49 rows belong to 8 different levels (electrode1, ...,electrode8). I want to split the table always at the row where ?electrode1? starts again so that I can export 7 individual dataframes (numbered ?dataframe1? to ?dataframe7?) which contain always

I am lousy at simple regex and I have not found a solution to a simple problem. I have a vector with some character values that I want to split. Sample data dd1 <- c( "XXY (mat harry)","XXY (jim bob)", "CAMP (joe blow)", "ALP (max jack)") Desired result dd2 <- data.frame( xx = c("XXY", "XXY", "CAMP",

...his mean BFD LD after 2.20 can support LLVMgold.so? Ld version on my system is: GNU ld (GNU Binutils for Ubuntu) 2.21.53.20110810 2. Gold only supports ELF. If BFD LD can support LLVMgold, can LTO be applied to COFF objects after recompiling the binutils with target==x86_64-pc-pe? Thanks!

The new linker is quickly becoming more than just an experiment. 64-bit COFF linker is mostly feature complete, and now we are having a direct translation of the COFF linker for ELF. Historically LLD has been suffered by over-designing and over-engineering. I don't want to repeat that again in the new codebase, so I'd like to be an owner of the new linkers (both for ELF and COFF), so that

...how R works (how programming languages work in general). Instead, the sequence is evaluated in the first place, and then the sign may apply as long as you provided something that can hold a sign. And an empty element has no sign, so the sign is lost.
