These functions are all methods
for class glm
or
summary.glm
objects.

residuals(object, type = c("deviance", "pearson", "working",

an object of class |

the type of residuals which should be returned.

further arguments passed to or from other methods. |
The references define the types of residuals: Davison & Snell is a good reference for the usages of each.
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.
