Hi, I have a data frame with several columns. Now I want to transfer the data into a new variable (also a data frame), but I only want a part of the data, defined by a rule ... for example; I have following data frame: row1 row2 row3 x 2 3 x 1 4 y 5 3 y 2 3 I know want a data frame, only with lines containing x in row1. I know how to do that for one row (f <- d$row2[d$row1=="x"]). But how can I do that for all rows in one step? So that I get this for f: row1 row2 row3 x 2 3 x 1 4

I guess this has a simple solution: I have matrix 'mat1' which has row and column names, e.g.: A B C row1 0 0 0 row2 0 0 0 .... rown 0 0 0 I have a another matrix 'mat2', essentially a subset of 'mat1' where the rownames are all in 'mat1' e.g.: B row3 5 row8 6 row54 7 I want to insert the values of matrix mat2 for column B (in reality it could be some or all of column names A, B or C, etc.) (same name in both matrices if that matters - rownames of mat2 guaranteed to be in mat1) into matrix mat1 where the rownames match, so final desired res...

Hi Friends, I am new to R. On R utility class pages, creating "named.list" is described with this command : new("named.list",a=1,b=2) For large matrix having two columns, such as : "row1" 2334 "row2" 347 "row3" 379 ... I want to create a named.list like : $row1 [1] 2334 $row2 [1] 347 ... Can anyone explain how "named.list" variable can be created by using two specified columns of a dataframe or matrix object, where one of the two columns is assigned as a name (string) and other as it...

...re preferred and colored green. I also want to print in each cell the numeric value, and I need to show row names. A crude example without the color: RowNames Col1 Col2 ---------------------------------------------- Row1 1 1 Row2 5 50 Row3 7.5 80 Row4 10 99 ...... Is there any R package that can do something similar? Can I create a plot that is a matrix of rectangles and get color and text that way? Any help is greatly appreciated.

...ution except > decompose-vectors? Ah, no, the TBAA thing is separate really. llvmpipe generally operates on 4 rows at a time, so some functions end up with patterns like: load <16 x i8> row0 ... load <16 x i8> row1 ... load <16 x i8> row2 ... load <16 x i8> row3 ... ... do stuff ... store <16 x i8> row0 ... store <16 x i8> row1 ... store <16 x i8> row2 ... store <16 x i8> row3 ... Since the row stride is variable, llvm doesn't have enough information to tell that these rows don't alias. So it has to keep the...

Hi, Richard, I think we are solving a same problem. I am working on shader language too. I am not satisfied with current binaries because vector operations are kept in llvm opt. glsl shader language has an operation called "swizzle". It can select sub-components of a vector. If a shader only takes components "xy" for a vec4. it's certainly wasteful to generate 4

Hello, I am working with a matrix of multilocus genotypes for ~180 individual snail samples, with substantial missing data. I am trying to calculate the pairwise genetic distance between individuals using the stats package 'dist' function, using euclidean distance. I took a subset of this dataset (3 samples x 3 loci) to test how euclidean distance is calculated: 3x3 subset used

You have a two-dimensional data frame.
