| .Spam {spam} | R Documentation |
.Spam is a list holding information used for
constructing and displaying spam objects.
.Spam
The user should only change eps, printsize,
imagesize and drop.
bcksl and safemode are rather developing flags.
It is the users responsibility to use a safemode=FALSE. In many
cases, all runs smoothly but there might be instances (especially when
assigning directly to slots) that crash R. The verification is done
with the functions icheck and dcheck.
eps=.Machine$double.eps |
values smaller than this are considered as zero. This is only used when creating spam objects. |
drop=FALSE |
default parameter for drop when subsetting |
printsize=100 |
the max number of elements of a matrix which we display as regular matrix. |
imagesize=10000 |
the max number of elements of a matrix we display
as regular matrix with image or display. Larger matrices are represented
as dots only. |
trivalues |
a flag whether to return the structure (default,
FALSE or the values themselves (TRUE) when returning the
upper and lower triangular part of a matrix. |
cex |
default dot size for image or display. |
version |
a list containing the (major and minor) version number and the release date. |
bcksl=TRUE |
default parameter for "solve" routines. FALSE
would solve the system without using the permutation. |
safemode=TRUE |
verify double and integer formats when constructing
spam objects. TRUE is safe but only slightly slower. |
