[R] 2 dimension convolve

Anybody know how to do a fast 2 dimension convolve in R? I used a traditional method, but it's very slow, even can not stand it! -- View this message in context: http://www.nabble.com/2-dimension-convolve-tp22440837p22440837.html Sent from the R help mailing list archive at Nabble.com.

[R] Is there any method to identify the distribution of a given dataset?

It's important to identify the distribution of a dataset before do analysis and inference. Is there any method to identify the distribution of a given dataset? For example, I want to identify a dataset belong to normal of poisson distribution, how can I do that? -- View this message in context:
