methods for class glm or
  summary.glm objects.
"family"(object, ...)
"residuals"(object, type = c("deviance", "pearson", "working", "response", "partial"), ...)glm, typically the result of
    a call to glm."deviance" (default), "pearson",
    "working", "response", and "partial".
    Can be abbreviated.The partial residuals are a matrix of working residuals, with each column formed by omitting a term from the model.
  How residuals treats cases with missing values in the original
  fit is determined by the na.action argument of that fit.
  If na.action = na.omit omitted cases will not appear in the
  residuals, whereas if na.action = na.exclude they will appear,
  with residual value NA.  See also naresid.
  For fits done with y = FALSE the response values are computed
  from other components.
