Browse other questions tagged r special-characters or ask your own question.

Although my Popular var is a factor of 2 values 0 and 1. Typical example is calculating the weighted mean of a variable MYVAR in a data frame using another variable WEIGHT for weights: m <- weighted.mean(tbl$MYVAR, w = tbl$WEIGHT, na.rm = TRUE) Suppose Is there a notion of causality in physical laws? If it doesn't: the model fit is over determined and there is no unique solution, so many of the parameter estimates are NA.
