[R] Time series - Spectral Clustering (kernlab)

[PA Roullet]

Hello everyone,

I have a question concerning specc function from kernlab.

I get this error :

> sc <- specc(c, centers = 3)
Error in seq.default(lsmin, (Re(log2(midmin)) - 0.5), stepm) : 
  'from' cannot be NA, NaN or infinite

when I try using specc using the data that I have joined to this message as .rda or .csv

Anyone got the slightest idea why I get this error and what i can do to resolve the problem ?

This problem only arise when I use matrix if I transform my matrix as a data frame I obtain other error that are also kind of strange :

> specc(dfTest, centers = 2)
Error: number of cluster centres must lie between 1 and nrow(x)
> specc(dfTest, centers = 3)
Error in .local(x, ...) : more cluster centers than data points.

Thanks a lot for your time and sorry if I did something wrong, first time posting here.
