R step-by-step execution
Hello!
I wouldl ike to ask you if R supports step by step execution. I have written
some nested loops and I would like to check on every step what are the values
of some variables. Printing all the variables just creates a really big output
of numbers.
Could you please give some debugging tutorial that included the aforementioned
functionalities?

Give me all operator
Hello is there in R any operator that give you all the data of a matrix
for example in matlab
x(2,3) returns the 2ndth row and 3rdth column
x(2,:) returns all the columns of the 2nd row.
In R now I would like to print all the
CRagent[[i]][2]
CRagent[[:]][2] doesnot work of course. Other option is to make a loop with an index i that spans from 1:last element of CRagent[[]] but this is not

plot inside function does not work
Hello everyone,
when I commit a plot using console(command line?) plot works fine. I have created a function that plots based on the input. This function is called plot_shad. When I call this function alone in the command line I get my plot.
Then I tried to use another function as depicted_below to do some calculation before calling the function that does the plotting.

Linear Integration
Hello
I would like to calculate a weighted line integral.
The integral is calculated by the cells that this lines trasverses (the small
cells belong to matrix (m*n) that represent the value that a specific area has.
I need to calculate the weights by finding out how much the line touches or
impinges inside a cell.
The weight is less if a line just touches one of the four edges of a square

3D plot with coordinates
Thanks. So after searching 4 hours last night it looks like that there is no R package that can do this right now. Any other ideas or suggestions might be helpful.RegardsAlex

3D plot with coordinates
Thanks Duncan for the replyI can not suppress anything these are radiation pattern measurements that are typically are taken at X,Y and Z planes. See an example here, where I want to plot the measurements for the red, green and blue planes (so the image below withouth the 3d green structure inside)https://www.researchgate.net/publication/258391165/figure/fig7/AS:322947316240401 at

Create weird type of sequences
Dear all,
I would like to create the following sequence of numbers
1 2 2 3 3 3 3 4 4 4 4 4 4 4 4 and so on (actually I double the number of same elements)....
the reason is that I want then to feed the sequence above to
tapply(myVector, weirSeq, FUN = mean)
and then average over those...
Could you please provide some guidance how I can create such a sequence in R?

Simple categorical scatter plot
New to R. I am trying to create a simple xy plot wherein the line
segment color is determined by a categorical column
The following does not change colors for me, probably because I don't
quite have a handle on either functions or value mapping syntax.
----------
time <- c(1, 2, 3, 7,10,11,14,16,20)
pressure <- c(0,10,20,20,50,18,60,65,90)

sp: proj4string has no impact
Hi all,
I'm faced with a problem applying the sp package: The projection argument in
readShapePoly(Shapefile,proj4string="CRS class argument")
e.g.: CRS("+proj=aea +lat_1=46 +lat_2=73 +lat_0=60 +lon_0=84 +x_0=0
+y_0=0 +ellps=clrk66 +units=m +no_defs")
doesn't have any impact on the plotted object. I also tested the simple
example:

Assigning values to several consecutives rows in a sequence while leaving some empty
Hello all,
I'm trying to group several consecutives rows (and assigning them the same
value) while leaving some of the rows empty (when a certain condition is not
fulfilled).
My data are locations (xy coordinates), the date/time at which they were
measured, and the time span between measures. Somehow simplified, they look
like this:

probes on udp port 500
Last couple of days some of my hosts were probed for UDP port 500 (IKE daemon,
used by IPSec for key exchange) from dialup IPs. Don't remember seeing similar
probes before. Some new vaulnerability that script kiddies (and pro crackers)
are trying out, or is this some old stuff? I do remember there were some
security problems with racoon in the past (that were fixed in current CentOS

Help me apply mapply
Hello all I would like to ask your help use mapply.
I have a function called findCell that takes two arguments(x,sr)
where x is a vector of size two (e.g x<-c(2,3) and sr is a matrix.
I would like to call many times the findCell function (thus I need mapply) for different x inputs but always for the same sr.
as x is a vector of size two (two cells) I want to pass inside inside the following

It appears that PHP config is somehow not functioning correctly.
