createGrid error

Hello,

I have an issue using createGrid function:

import('5th-2.dxf', 'CODA_5th')
createGrid('CODA_5th', 'CODA_5th_VGA', gridSize=7)

Error in depthmapXcli(params, cliPath, verbose) :
Initial checks... Chosen grid spacing 7 is outside of the expected interval of 0.02 <= spacing <= 4

This is strange because the exact same lines worked without error a few weeks ago. I reinstalled the Rdepthmap just in case, but it returned the same error.

Thanks,
Yeinn

prepVGA and VGA parameters

Hi there! Firstly, thank you so much for developing the R depthmap. This was very needed! I'm trying to use this to run spatial analysis on a building.

I have several questions about perpVGA and VGA functions:

• In prepVGA, does the 'gridsize' equal to 'grid spacing' in depthmapX?
• What does the fillx and filly do exactly? I'm setting them as both 10, but I don't see any difference in the result.
• In perpVGA, why does the maxVisibility has a limit of 400? When I run the same analysis in depthmapX, the visibility hits even over 600.
• If I run the analysis with maxVisibility of 400 anyway, it returns an error message. Let me show you the whole syntax that I was running.

prepVGA('CODA', 'CODA_VGA', 10, 10, gridSize = 5, maxVisibility = 400, makeBoundaryGraph = FALSE, makeGraph = TRUE)
VGA('CODA_VGA', 'VGAout', "visibility-global", 40)
CODA_result <- getPointmapData('VGAout', scale = 1, cliPath = getDefaultCLILocation(), verbose = FALSE)

and then I get:

Error in points2grid(points, tolerance, round) :
cannot derive grid parameters from a single point!

Again, thanks a lot for developing this!

can‘t install rdepthmap

when I use tools to install rdepthmap， the Rstudio tells me that it can not find rdepthmap. I also tried the write your remind code to install rdepthmap ，but it doesn't work either.
