The qurey about kolmogorov-smirnov test & adding the trendline to graph
I am hereby forwarding the data & method use to calculate the
Kolmogorov-Smirnov goodness of fit test made manually by me in R
launguage which deffers with the actual inbuilt formula as shown below.
Further I have plot the graph in R. In that graph how to add trendline
(i.e. straight line passing through maximum points in plot) to a Plot.

serialize() takes too long when serializing to a raw vector
Hello,
R version 2.4.1 (2006-12-18)
i386-pc-mingw32
Calling serialize() with a NULL connection serializes it to a raw vector. However, when the object to be serialized is large, it takes a very long time:
> system.time( serialize(matrix(0, 1000, 1000), NULL) )
[1] 38.25 40.73 81.54 NA NA
> system.time( serialize(matrix(0, 2000, 2000), NULL) )
[1] 609.72 664.75 1318.57 NA
