ctmmweb: Web App For ctmm Package

Variograms of individuals in current subset are plotted here.

The figure height and columns of figures in control box are applied to plots in variogram, home range, occurrence page too.
The slider control the Time-lag range in plots. It's in Logarithmic scale, ranged from 0.001 (0.1%) to 1 (100%) of the total range. Some browser in certain platform may have compatibility issues and showing the labels wrong. Firefox and Chrome are recommended browsers.
The units of X (Time-lag) and Y (Semi-variance) may change according to data to better represent the values.
Absolute mode operate on the max Time-lag range individual in group, and all others scaled with same X, Y axes for easier comparison.
Relative mode zoom every plot by fraction of their own Time-lag range. The X, Y axes are not synced.
Guesstimate will add a layer of model fit with parameters determined automatically. In this state, you can further fine-tune the parameters by selecting individual in the drop down list.
- The drop down list support search filter and direct editing.
- There will be a pop up window for fine-tune parameters.
- Center current values will update sliders 2, 3, 4 range to twice of current value. This can extend range with slider in right end, or increase resolution with slider in left end.
- Apply butto will accept adjusted parameters and update the variogram.
Modeled mode is enabled after models are fitted and selected.
Clicking Fit Models will start to fit possible models for every individual in current subset. It could be time taking so it need to be manually activated.
- Depend on platform (Windows/Mac/Linux), different parallel processes are used. There will be a time report in console when running app in local mode.
- If the app was terminated by force, there could be forked R sessions remained active. It's better to clean up all R sessions in your system's task manager after force quitting the app.
- data.table is known to have conflict with mclapply in Mac R 3.4 with openMP. The error is somewhat random, restart R session can often make it dissappear.
