cumsum in 3d arrays
Hello!
Is it posible to apply /cumsum()/ along the 3rd dimension of 3D array?
Something like matrlab function - /cumsum (*A*,dim)/ which returns the
cumulative sum of the elements along the dimension of *A* specified by
scalar dim.
Thanks in advance

fUtilities removed
When setting up my new machine, I had the surprise to see that "Package
'fUtilities' was removed from the CRAN repository."
This is problematic for my work. I use many of its functions, and it will
complicate things a lot if other programmers want to use my previous code in
the future. Plus, nowhere can I find the justification for its removal.
Thanks for any info on this

Interpolating spline problems and akima
Hi everyone
I was using spline to interpolate single or two consecutive missing data points
in time series. However, when it comes to longer gaps in the data the spline
function generate new data for both my known and unknown data (see below).
Aside from not understanding why this happens, I thought thought I might try
function "aspline" in library (akima). However, I cannot install or

Using Akima with nearly-gridded data
I am using the Akima interpolation package to generate an interpolated
color contour plot. It is working very well, except for one problem.
The data that I have represents real-time readings from a thermistor
string vs. time, so the data points are often very nearly in a
rectangular array, since the thermistors are read at regular time
intervals and they are equally spaced physically.

AKIMA color contouring
R Users,
I am using the AKIMA contrib package to generate a 2D colored
contour plot.
The code generates a contour value color legend adjacent the plot
based on the range of
Z values in the plot.
Is there some way to make the association between Z values and
color scale absolute
rather than relative i.e., I want dark green to always mean Z = 4.00 even
if I don't

akima interpolation and triangulation question
Dear all;
First of all, this is probably a more conceptual question than a
R-related one, but still want to give it a try. When working with the
interpolation function "interp" from the package akima and the
triangulation function "tri.mesh" from package tripack I've got NA's
for the interpolation and "error" for the triangulation. The data is
arranged in a

akima interp results to zero with less than 10 values
Dear all
I have this table
> dput(mat)
mat <- structure(c(2, 16, 9, 2, 16, 1, 1, 4, 7, 7, 44.52, 42.8, 43.54,
40.26, 40.09), dim = c(5L, 3L))
And I want to calculate result for contour or image plots as I did few years
ago.
However interp does not compute the z values and gives me zeros in z matrix.

akima::interp "scales of x and y are too dissimilar"
Dear R users,
I want to do a fitted.contour plot of selected columns of a dataframe M with
M$AM and M$Irradiance as x and y axes respectively. The level of the contour
shall be determined by M$PR.
Some words on my data first. Dataframe M looks like:
head(M$Irradiance)
[1] 293 350 412 419 477 509
head(M$AM)
[1] 2.407 2.161 1.964 1.805 1.673 1.563

akima interp results to zero with less than 10 values
The akima package has a problematic license (it doesn't allow commercial
use), so it's been recommended that people use the interp package
instead. When I use interp::interp instead of akima::interp, I get
reasonable output from your example.
So that's another reason to drop akima...

akima 0.4-5, interpp() bug = COMMON block problem
Hi,
I'm currently hunting a bug in the akima library, especially in the code
behind the interpp.old function (bi-variate linear interpolation).
It is based on a triangulation algorithm, interpolation at a given point
needs to know the triangle which contains this point, then the
interpolation is a straightforward calculation based on the three
vertexes.
The problem is: Sometimes the triangle

AKIMA or translating to FORTRAN a R function calling a FORTRAN routine
Hi,
I am hired to translate into FORTRAN R functions. It works great and my customer is happy. I am going to translate a function that call aspline in the library AKIMA.
This function call 2 FORTRAN routines that must be include (I guess) in the package AKIMA. And I have some questions.
Is the fortran code really included in the R package AKIMA ?
In other word, do I have a mean to call these 2

CDR with unix time.
Good morning everyone.
I wonder if it is possible, without touching the source code, to Asterisk
save the cdr with date in unix time instead of the default date. It's
possible?
Thanks in advance,
