Adding two or more columns of a data frame for each row when NAs are present.
I am fairly new to R and would like help with the problem below. I am trying to sum and count several rows in the data frame yy below. All works well as in example 1.

Standardized residual variances in SEM
Hello, I'm using the "sem" package to do a confirmatory factor analysis on data collected with a questionnaire. In the model, there is a unique factor G and 23 items. I would like to calculate the standardized residual variance of the observed variables. "Sem" only gives the residual variance with the "summary" function, or the standardized loadings with the

[PATCH] Optimize silk_LPC_inverse_pred_gain() for ARM NEON
