...mns. Also, I realized that I actually need to pull out the row that is associated with that variable as well, and so perhaps the section inside {} needs to be something like: {x=x[-col(x),-col(x)] Any idea on how to do this?

...with v2.0 all secure_delete utilities work in secure mode (38 special passes). To lower the security and make it faster, you may add -l (one random pass, on 0xff pass) or -ll (one 0xff pass) to the parameters. The secure overwrite mode works that way: 1x overwrite with 0xff 5x random passes 28x overwriting with special values to make the recovery from MFM and RLL encoded harddisks hard/impossible - see Gutmann's paper on that which is also included. 5x random passes __________________________________________________ Do You Yahoo!?

I do not understand, from a PCA point of view, the option center=F of prcomp() According to the help page, the calculation in prcomp() "is done by a singular value decomposition of the (centered and possibly scaled) data matrix, not by using eigen on the covariance matrix" (as it's done by princomp()) . "This is generally the preferred method for numerical accuracy"

Hello, I am trying to find the analytical solution to this differential equation dR/dt = k1*(R^k2)*(1-(R/Rmax)); R(0) = Ro k1 and k2 are parameters that need to fitted, while Ro and Rmax are the baseline and max value (which can be fitted or fixed). The response (R) increases initially at an exponential rate governed by the rate constants k1 and k2. Response has a S-shaped curve as a function
