Hi Everyone, I have a question regarding the construction of 3D graphs in 'R', BUT these graphs also need to illustrate movement (with time) of the prostate gland (using radiological techniques). I am not sure how to do this in 'R' although I'm sure there is some way of doing it. Below, I have copied and pasted some of the data with which I'm working on. The data

A minimal familiarity with the adehabitat code could be desirable. Mentor Damiano G. Preatoni, PhD. Research Associate Unit? di...

Hello here, I need to find an idea to solve a problem I manage Events which are of kind :arrival or :departure At first the two kind of events was unrelated but my client want to see the :departure belonging to the :arrival and vice versa. I''m searching for a solution to implement this ''link''. I''ve thought about an integer column containing an uniq id for

Hi, I am trying to simulate animal movement in a gridded landscape made up of cells. At each time step (iteration), the animal moves from one cell to another in a random fashion. This is how I am simulating movement, where a and b are the x,y co-ordinates of the animal at the previous time step: for (i in 1:no.of.steps){ direction <- sample(1:8, 1) if(direction == 1){ a <- a b <- b -

...witching Bayesian Vector Autoregression Models (MSBVAR) that is used to examine the effect of a large economy?s stock exchange movement on a small economy?s stock exchange movement. The foreign stock exchange index follows its own dynamics (an AR process is used as a proxy). Turkish stock exchange movements are affected by its own lag and movements of the foreign stock exchange. Therefore, the foreign stock exchange can be thought to have an exogenous affect on the Turkish stock exchange. None of the lag variables of the Turkish stock exchange determine foreign stock exchange; however, lag values and...

Dear list, ? I am intersted in estimating movement based kernel densities for fish that were relocated at fixed receivers positioned along the coast. These data tend to display both a drift movment between receivers and a random movement component that can be estimated from the mean and the variance of the transit time between receivers. ?If I obtain an estimate of the diffusion coefficient from

Hi I'm just wondering what the status is on the new movement architecture that I think David mentioned a few months ago. The point was to get more predictable and accurate movement in the plugins. Since the current method recomputes speed and direction every "timestep". So the movemnt is actually computed on the fly, instead of having a predetermined path which is

I have data on current and previous location of individuals. I would like to have a matrix with bilateral movement between locations. I would like the final output to look like the second table below. I have tried using crosstab() from the ecodist but I do not have another variable to measure the flow. Ultimately I would like to compute the probability of movement between cities (movement to

Dear list, I am trying to program semi-random movement within a circle, with no particles leaving the circle. I would like them to bounce back when they come to close to the wall, but I don't seem to be able to get this right. Would somebody kindly give me a hint ? This is my code so far, the particle starts at some point and moves towards the wall, but I don't get the "bouncing

Hi, my mouse doesn't work correctly in many games (not all). I'm using Ubuntu 10.10 and the wine1.3 (from the launchpad package). This concerns Need for Speed 2, Star Trek Bridge Commander and some others. In Star Trek Bridge Commander the mouse doesn't seem to have a right x-axis and I'm not able to click on anything. Using the Keyboard to move the cursor won't do as well. In

hi there I hope you can help me I'm doing a boxplot and I'm trying to change the y-axis from seconds to minutes I do this: boxplot ( time~movement*scene, ylab = "Time (seconds)", xlab = "Condition") but seconds goes from 0 to 900 and I'm looking to change it into minutes I've been though the manuals but I don't know what you call this function so its hard

Hi I think this is mostly a question of preference for my part, but I think it would give an overall better quality feel. What I'm talking about is mostly the movement it uses. As I've come to understand, it uses velocity and direction, and a target point. This means that it updates it velocity and direction every X seconds (timestep), and gives it the possibility to be

or in base R : ?xtabs ?? as in: xtabs(~previous_location + current_location,data=x) (You can convert the 0s to NA's if you like) Cheers, Bert Bert Gunter "The trouble with having an open mind is that people keep coming along and sticking things into it." -- Opus (aka Berkeley Breathed in his "Bloom County" comic strip ) On Tue, May 8, 2018 at 9:21 AM, Huzefa

Dear Miluji, If I understand correctly, this should get you what you need. temp1 <- structure(list(id = 101:115, current_location = structure(c(2L, 8L, 8L, 3L, 6L, 5L, 1L, 2L, 7L, 4L, 2L, 8L, 8L, 3L, 6L), .Label = c("Austin", "Boston", "Cambridge", "Durham", "Houston", "Lynn", "New Orleans", "New York"), class =

Hello, I''d like to know if this is possible. Say you have a sortable list like so: <ul id="mysort"> <li>one</li> <li>two</li> <li>three -- A</li> <li>four</li> <li>five -- B</li> </ul> Is there any way to restrict the movement of "three -- A" and "five -- B" such that

I would have thought that the file movement from one FS to another within the same pool would be almost instantaneous. Why does it take to platter for such a movement? # time cp /tmp/blockfile /pcshare/1gb-tempfile real 0m5.758s # time mv /pcshare/1gb-tempfile . real 0m4.501s Both FSs are with compression=off. /tmp is RAM. -devsk -- This message posted from opensolaris.org

I just noticed when using 2.6.1, 2.6.2 (2008-02-08), 2.6.2pat (2008-02-21 r44582), and 2.6.2pat (2008-03-24 r44975) on my poor old Celeron D330 (2.6 GHz; 3.5 years old) running Windows XP, that the mouse cursor appears to be redrawn more sluggishly when the pointer is over R windows graphics devices than over the R console window or other applications' windows. The slowdown seems to start only

...for my own personal growth and javascript goodness. It is a drag and drop game, and it may not be 100% possible to do everything I want with it. But that has not stopped me from trying thus far. The project: a javascript drag-n-drop chess game. The goal: Make a chess game that can track movements for players, make sure moves are valid, remove pieces on capture. I figure stalemate/checkmate calculations can be left to the players for now. What do I have done? Not a ton. I got stuck. Which is why I need you all. What is my problem(s)? Simply, events.
