dot

I have a collection of digraphs encoded in the DOT language. I want to construct a graph-of-graphs such that each node in the super-graph is one of these digraphs. Is there a way to do this within the GraphViz framework? I know that gvpack will allow me to assemble multiple graphs into one .dot file. But I don't know if it will allow me to declare edges between those graphs. The short answer is that gvpack does not declare edges between the sub-graphs. Indeed, when there are common node names between sub-graphs, gvpack renames them to avoid clashes. However, that is fixable. For example, given

Consider the following setup. namespace ns { struct type { int var; }; } In this case, to refer to the structure, which is a member of a namespace, you use :: . To access the variable in an object of type type , you use . . ns::type obj; obj.var = 1; 回答2: Another way to think of the quad-dot '::' is the scope resolution

The info is in names=paste("dot", 1:4, sep="") I have tried with no success the following panel.text(x=X2, y=X1, names) or, using directlabels library(directlabels) p=xyplot(X2~X1,data=data.frame(X1, X2), pch=20, group=names, cex=1:4) direct.label(p,smart.grid,FALSE) but I don't like it much because I had to split into groups

Thanks! 回答1: Escape the . : sed 's/foo\./foo_/g' file.php Example: ~ $ cat test . txt foo . bar ~ $ sed 's/foo\./foo_/g' test . txt foo_bar 回答2: Escape the dot with a \ sed 's/foo\./foo_/g' file . php If you find the combination of / and \ confusing you can use another 'separator' character sed 's#foo\.#foo_#g The 2nd character after the s can be anything and sed will use that character as a separator. 回答3: Interestingly, if you

X, t are Numpy ndarray. 回答1: Probably there's something wrong with the input values for X and/or T. The function from the question works ok: import numpy as np from math import e def sigmoid(X, T): return 1.0 / (1.0 + np.exp(-1.0 * np.dot(X, T))) X = np.array([[1, 2, 3], [5, 0, 0]]) T = np.array([[1, 2], [1, 1], [4, 4]]) print X.dot(T) print # Just to see if values are ok

(note that I'm on Windows, not linux) 回答1: type: dot -Tps filename.dot -o outfile.ps If you want to use the dot renderer. There are alternatives like neato and twopi. If graphiz isn't in your path, figure out where it is installed and run it from there. You can change the output format by varying the extension of the filename specified with -o .
