Webglm is used to fit generalized linear models, specified by giving a symbolic description of the linear predictor and a description of the error distribution. WebIn these cases R generates a vector of ones to represent the binomial denominators. Alternatively, the response can be a matrix where the first column is the number of “successes” and the second column is the number of “failures”. In this case R adds the two columns together to produce the correct binomial denominator.
