Hi all
I have a numeric matrix
data I scale it linearly to be able to reduce it to unsigned 8bits. I
create a raster object from scaled data and setting data type to
INT1U.I want to export this data to png indexed
Hello all
I am manipulating some data and wish to expand/unmerge (i.e. do the opposite of
aggregate) rows in a data matrix based on the values in a particular column and
a seperator, e.g.
Col1Col2
n1;n2 6
...separating by ; becomes
Col1Col2
num16
num26
Any ideas?
Also
Try this:
as.data.frame(sapply(sapply(DF, as.character, simplify = FALSE), strsplit, ;))

(rows) I want to scale the data between 0 (representing the minimum value in
that row) and 1 (representing the maximum value in that row). I was wondering
if there is a simple function anywhere that does

Try this,
library(ggplot2)
apply(matrix(10*rnorm(10),2), 1, ggplot2::rescale)
