[R] R installation Problem

2013-07-08 Thread sridhar srinivasan
Dear R Developers,

I have two doubts related to R

1. i try to install R package 3.0 in my linux system ./configure.
it gives Error as
configure: error: --with-readline=yes (default) and headers/libs are not
available

2. This is related to library
i am trying to install the library(cummeRbund) in differeent R version in
another system
it shows Error as

> source("http://bioconductor.org/biocLite.R";)
Error in file(con, "r") : cannot open the connection
In addition: Warning message:
In file(con, "r") : unable to resolve 'bioconductor.org'
> biocLite("cummeRbund")
Error: could not find function "biocLite"

Could anybody suggest on the same..

Thanks
Sridhar

[R] Frequency count of Boolean pattern in 4 vectors.

2013-06-01 Thread Sridhar Iyer
I need to do this on very large datasets ( > a few million data points). So
seeking help in figuring out an implementation of the task.

Input 4 vectors which contain values as 0 or 1. (as integers, not boolean
bits)
vec_A = ( 0, 1, 0, 0, .. 1, 0, 1, 0)   etc
vec_B = (0,0,1,1.)
vec_C, vec_D  (similar to above)
All four vectors are same length.

I need to compute frequency count of the boolean literals for DCBA,
DCBA

0001
0010
0011
..
..


Questions:
a) Is there a mechanism for combining the 4 vectors (in integer formats)
into 4 bits of a new vector or some other
type? (or treat them as boolean values true/false instead of 0 or 1
integers).
b) what is the most efficient mechanism for obtaining the frequency count of
each of the sixteen Boolean
combinations?

I need to do this frequently on large datasets. So am trying to get an
efficient implementation (instead of
a quick and dirty scheme). Thank you very very much in advance.

[R] R- merging two matrix

2012-09-09 Thread Sridhar Iyer
Hi,

I have two matrices.  (same size, same number of rows,
same names for the rows  - one has data in sorted
order, another one master data in unsorted order. I need to
combine both).

Rows names of Matrix A
P, Q, R, S, T, U, V ...(some order) - each row has 4 values

Row names of Matrix B (same as B, but in a different (sorted) order)

Q, P, T, U, V, ... (same names, but different order) - has one value

I need to create a master matrix with data from these two.

How do I take the numerical value for Q (from Matrix B) and append it to the
values in Matrix A. (so it becomes the 5th value in the master file)

Thank you very much

Srid Iyer
