[R] applying wilcox.test to every combination of rows in a matrix (pairwise)

Re: [R] expand dataframe but time gap is not the same

You can use the approx() function (in that stats package) to put 5 equally spaced times between your high and low water times. E.g., in the following 'tmp' will be your interpolated times, in seconds since 1970, which I clumsily convert to POSIX times (I can never remember how to deal with time

Re: [R] applying wilcox.test to every combination of rows in a matrix (pairwise)

If I understand correctly, this should do what you want, but there will be warnings for each test about p-values not being exact because you reuse the pc1.eigv vector for each row so that each value occurs twice: First we can simplify the original comparisons by using the formula mode for

No, no correrán en paralelo si usas los SVM de paquetes como e1071. No obstante, tienes, por un lado, los trucos habituales para hacer algo "parecido" a SVM o "basado" en SVM pero que no sea SVM. Si es que eso te vale. Puedes probar a hacerlo con mllib (sobre Spark), como aquí
