Hello everyone.
I have created a 100*100 matrix in R.
Let's now say that I have a line that starts from (2,3) point and ends to the
(62,34) point. In other words this line starts at cell (2,3) and ends at cell
(62,34).
Is it possible to get by some R function all the matrix's cells that this li
Thank you very much. I am trying to execute it line by line to get some
understanding how this works.
Could you please explain me what these two lines do?
tie <- m[,2] == c(-Inf, m[-nrow(m),2])
m <- m[ !tie, ]
I would like to thank you in advance for your help
Best Regards

Hello I have some strange output from R and I try to understand how R works.
Could you please help me with that?
temp <- rbind (c(10,1),c(99,98))
> temp
[,1] [,2]
[1,] 101
[2,] 99 98
> dist(temp)
1
2 131.6435
> sqrt(dist(temp))
1
2 11.47360
so far so good

?dist
BTW, to me this does not happens.
x <- matrix(rnorm(100), nrow=5)
d <- dist(x)
1/sqrt(d)
1/sqrt(dist(x))
Hope it helps

But it seems that the floor function (ceiling, round too) create more dots in
the matrix that line really "touches".
unique( floor( cbind( seq(2,62, by=0.1), linefn(seq(2,62, by=0.1)) ) ) )
You can see that in the picture below

Alaios,
Try
as.data.frame(table(x[,1], x[,2))
where x is your matrix.
HTH
My bad :(
unfortunately does not work correct.
This is some of the output of the table
..
[494,] 50 27
[495,] 50 27
[496,] 50 27
[497,] 50 28
[498,] 50 28
[499,] 50 28
[500,] 50 28
[501,] 51 28
[502,] 51 28
[503,] 51 28
[504,] 51 28
[505,]
You are pretty good.
Worked nicely :)
Thanks!

So try this :

My bad :(

more you are in a cell the higher the
weight will be.

Hello everyone,
I need some help with lists inside lists (a good way to emulate a struct)\
Assume that there is a small list called fred:
fred <- list(happy = 1:10, name = "squash")
and a big list called bigfred that includes fred list 5 times
bigfred <- rep(fred,5)
Is it possible somehow to i

Hello.
I want to print the value a matrix has. The matrix's size is not too big
(100*100 cells). I tried print(matrixname) but as it does not fit very well on
my screen R splits it into several small matrixes that do overflow my screen.

I need some advice if the following might be easier implemented.

Hello
I would like to calculate a weighted line integral.
The integral is calculated by the cells that this lines trasverses (the small

Just to confirm that it works. Thanks for help.

Yes I had this conversation of how to find the cells that are touched.
I did that with these two lines:

No, because I thought something that might be easier.
If you see the image again you might notice that the proportions I am
looking for might also be found by using the hypotenuse which is the same
(as all squares are triangles) by finding the adjacent. The adjacent are
easier to be found by track
