.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. |
