| html3D {made4} | R Documentation |
html3D produces a pdb file that can be viewed using the freeware protein structure viewer Rasmol
and a html web page with a 3D graph that can be rotated and manipulated in a web browser that
supports the chime web browser plug-in.
html3D(df, classvec = NULL, writepdb = FALSE, filenamebase = "output",
writehtml = FALSE, title = NULL, scaled=TRUE,xyz.axes=c(1:3) ...)
df |
A matrix or data.frame containing the x,y,z coordinates.
Typically the output from bga such as the $ls or $co files, or other xyz
coordinates ($li or $co) produced by PCA, COA or other dudi
|
classvec |
factor or vector which describes classes in the df. Default is NULL.
If specified each group will be coloured in contrasting colours |
writepdb |
Logical. The default is FALSE. If TRUE a file will be saved which can be read into Rasmol. |
writehtml |
Logical. The default is FALSE, If TRUE a web html file will be saved which can be viewed in any web browser than supports chime. |
filenamebase |
Character. The basename of the html or pdb file(s) to be saved. The default is "output", which will save files output.pdb, output.html, if writepdb or writehtml are TRUE respectively. |
title |
Character, the title (header) of the web page saved if writehtml is TRUE. The default is NULL. |
scaled |
Logical indicating whether the data should be scaled for best fit. The default is TRUE |
xyz.axes |
|
... |
further arguments passed to or from other methods |
Produces a html file, of a 3D graph which can be rotated using the FREEWARE chime (win, MacOS). Chime can be downloaded from http://www.mdlchime.com/.
html3D will colour samples by classvec if given one, and will produce chime script to highlight groups,
spin on/off, and include button for restore for example see http://bioinf.ucd.ie/research/BGA/supplement.html
html3d calls chime3D to produce the html web page with a 3D graph.
html3D produces the pdb output file which can be read in Rasmol or other molecular structure viewers.
html3D produces a html file with a 3D graph that can be rotated and manipulated in a web browser that
supports the chime web browser plug-in.
Note chime is only available on windows or Mac OS currently. Using the chime plug-in on Linux is slightly complicated but is available if the CrossOver Plug-in is installed. Instructions on installing this and chime on Linux are available at http://mirrors.rcsb.org/SMS/STINGm/help/chime_linux.html
If you wish to view a 3D graph in Rasmol, you will need to execute a Rasmol script similar to
load pdbfilename.pdb; set axes on; select off; connect;set ambient 40; rotate x 180; select *; spacefill 40
html3D calls chime3D to produce the html file from the pdb file.
