Filling a covariance matrix
useRs ? I?m working with the attached data that contains one year?s worth of sub-daily observations of flow (?Q?) and specific conductance (?SC?, a surrogate for concentration) at a point in a stream. The R code posted below shows the extent of data processing thus far. My goal is to create a covariance matrix that takes on the following form: Q1 Q2 ? Q365 SC1 SC2 ? SC365 Q1 Q2 ? Q365
