...moved, but the row headers are the numbers 1 to 1000 and they will remain in the matrix. In the previous post I mentioned that R makes the 1000 columns and the 101 rows into a "101x0 character matrix" once I removed the 1st column "Time (day)". Instead I want this to be a "101x1000 double matrix". What needs to be done to make the .csv into a double matrix rather than a character matrix when the first row is all zeros (0s)? Thank-you.

...v("1000Samples_Vsim.csv", header = TRUE, sep =",") # see data below Vobsr <- as.matrix(Vobsr[,-1]) # remove column 1 from analysis thus Vobsr is 101x1 double matrix (column 1 is date information) Vsimr <- as.matrix(Vsimr[,-1]) # remove column 1 from analysis thus Vsimr is 101x1000 double matrix (column 1 is date information) How can I subtract each row in "Vsimr" from each row in "Vobsr" (Vobsr - Vsimr)? That is the problem that I am having that keeps me from using the following code below for NSE (Nash-Sutcliffe efficiency): NSE(Vobsr,Vsimr) NSE = 1 -...
