Matrix to "database" -- best practices/efficiency?
I have a matrix of, say, M and N dimensions:
my_matrix=matrix(c(1:60),nrow=6,ncol=10)
I have two "id" vectors corresponding to the rows and columns, e.g.:
id_m=seq(10,60,by=10)
id_n=seq(100,1000,by=100)
I would like to create a "proper" database (let's say a data.frame for
this example -- i'm going to be loading these into an SQLite database,
but we'll leave

red-black-green color palette?
I'm working on some heatmaps, and the person I'm working with would
prefer a red-black-green color palette (red denoting gene induction and
green denoting gene repression). Does such a palette exist already?
If not, is there an easy way to create one?
Thanks,
Jake

Hi R-users
I can not change the name of one column only of my matrix.
my_matrix <- matrix (1:12,ncol=3)
colnames(my_matrix)[1] <- 'myname'
Error in dimnames(x) <- dn :

Flexclust barchart issue when mcol=NULL (PR#14150)
Full_Name: Chris Hane
Version: 2.10.1
OS: Windows
Submission from: (NULL) (198.203.181.181)
When using barchart in the flexcust package, setting mcol=NULL to avoid the
lollipops causes an error. Each panel shows the text message "Error using
packet n replacement has length zero." where n is the panel number.

Getting an error calling MASS::boxcox in a function
Dear Ron and Bert,
First (and without considering why one would want to do this, e.g.,
adding a start of 1 to the data), the following works for me:
------ snip ------
> library(MASS)
> BoxCoxLambda <- function(z){
+ b <- boxcox(z + 1 ~ 1,
+ lambda = seq(-5, 5, length.out = 101),
+ plotit = FALSE)
+ b$x[which.max(b$y)]
+ }

Printing to screen a matrix or data.frame in one chunk (not splitting columns)
Hello,
I saw this nice trick I want to replicate but I lost the source and I hope
one of you can point me to the solution. My problem is that I don't know
the correct words to query this.
When I print to screen a matrix or data.frame the columns are split and
printed below the previous ones; even though I have plenty of screen left.
E.g.,
> my_matrix = matrix(runif(30),nrow=3,ncol=10)

Thanks John.

a formula or fitted model object. Currently only lm and aov objects are handled.

I read that as saying that
boxcox(lm(z+1 ~ 1),...)
should run without error. But it didn't. And perhaps here's why:
BoxCoxLambda <- function(z){
b <- MASS:::boxcox.lm(lm(z+1 ~ 1), lambda = seq(-5, 5,

Getting an error calling MASS::boxcox in a function
No, I'm afraid I'm wrong. Something went wrong with my R session and gave
me incorrect answers. After restarting, I continued to get the same error
as you did with my supposed "fix." So just ignore what I said and sorry for
the noise.

Getting an error calling MASS::boxcox in a function
Hi,
Firstly, apologies as I have posted this on community.rstudio.com too.
I want to optimise a Box-Cox transformation on columns of a matrix (ie, a unique lambda for each column). So I wrote a function that includes the call to MASS::boxcox in order that it can be applied to each column easily. Except that I'm getting an error when calling the function. If I just extract a column of the

Getting an error calling MASS::boxcox in a function
Try this for your function:
BoxCoxLambda <- function(z){
y <- z
b <- boxcox(y + 1 ~ 1,lambda = seq(-5, 5, length.out = 61), plotit =
FALSE)
b$x[which.max(b$y)] # best lambda
}
***I think*** (corrections and clarification strongly welcomed!) that `~`
(the formula function) is looking for 'z' in the GlobalEnv, the caller of
apply(), and not finding it. It finds

How to save heatmap as image or pdf
Hello Everyone,
I am using R for creating heatmap from a square matrix. Below is my script
to do so
my_map <- read.csv("Desktop/input.csv", sep=",")
my_matrix <- data.matrix(my_map)
my_heatmap <- heatmap(my_matrix, Rowv=NA, Colv=NA, col = cm.colors(256),
scale="column", margins=c(5,10))
I get a beautiful plot as output, but I could not save this plot

Principal componet plot from lower triangular matrix file
Hi,
I have a comma separated file with element names in first column like shown
below :
Name_1,0
Name_2,0.8878,0
Name_3,0.6777,0.7643,0
Name_4,0.9844,0.1234,0.1414,0
Original data is a 10000x10000 symmetric matrix (600 MB). To reduce file
size, I have minimized matrix to only lower triangle. Is there a (memory)
efficient way to 1) read file 2) compute first and second principal
components and

Fixed size permutations
I'm using functions to return a matrix of all permutations of a
specified size from a larger list for predictor selection.
For each predictor size I use a seperate function like this:
bag2 <- function(n) {
rl <- c()
for (i1 in seq(n)) {
for (i2 in seq(n)) {
if (length(unique(c(i1,i2)))==1) {next}
rl <- cbind(rl,matrix(c(i1,i2)))
}
}
