Estimating model parameters for system of equations
Hi all,
I'm trying to estimate model parameters in R for a pretty simple system of
equations, but I'm having trouble. Here is the system of equations (all
derivatives):
eqAlgae <- (u_Amax * C_A) * (1 - (Q_Amin / Q_A))
eqQuota <- (p_max * R_V) / (K_p + R_V) - ((Q_A-Q_Amin)*u_Amax)
eqResource <- -C_A * (p_max * R_V) / (K_p + R_V)
eqSystem <- list(C_A = eqAlgae, Q_A = eqQuota, R_V = eqResource)
I want to estimate u_Amax, Q_Amin, p_max and Q_Amin with the data I've
collected using least squa...

concatenating column names in a loop
..."1"
x[1,2] <- "2"
x[1,3] <- "3"
I would like to create a new matrix with column names based on the column names
in x. Specifically, I would like the column names in y to be "q_" plus the
corresponding column name in x. So y[,1] should be named "q_a", y[,2] should be
names "q_b", and y[,3] should be named "q_c".
Here is the code I am trying:
y <- matrix(nrow = nrow(x), ncol = ncol(x))
for (i in 1:ncol(x)){
colnames(y)[i] <- paste("q_", (colnames(x)[i]), sep = "")
}
Alas, it does not...

Rebuild of kernel 2.6.9-67.0.20.EL failure
Hello list.
I'm trying to rebuild the 2.6.9.67.0.20.EL kernel, but it fails even without
modifications.
How did I try it?
Created a (non-root) build environment (not a mock )
Installed the kernel.scr.rpm and did a
rpmbuild -ba --target=`uname -m` kernel-2.6.spec 2> prep-err.log | tee
prep-out.log
The build failed at the end:
Processing files: kernel-xenU-devel-2.6.9-67.0.20.EL
