Slice an XInteger or XDouble object
The slice methods for XInteger and
XDouble objects create views corresponding to the indices where
the data are within the specified bounds. The views are returned in a
XIntegerViews or XDoubleViews object.
## S4 method for signature 'integer'
slice(x, lower=-.Machine$integer.max, upper=.Machine$integer.max)
## S4 method for signature 'XInteger'
slice(x, lower=-.Machine$integer.max, upper=.Machine$integer.max)
## S4 method for signature 'numeric'
slice(x, lower=-Inf, upper=Inf,
includeLower=TRUE, includeUpper=TRUE, rangesOnly=FALSE)
## S4 method for signature 'XDouble'
slice(x, lower=-.Machine$double.xmax, upper=.Machine$double.xmax,
includeLower=TRUE, includeUpper=TRUE, rangesOnly=FALSE)x |
An XInteger or XDouble object. Alternatively, it can also be an integer or numeric vector. |
lower, upper |
The lower and upper bounds for the slice. |
includeLower, includeUpper |
Logical indicating whether or not the specified boundary is open or closed. |
rangesOnly |
A logical indicating whether or not to drop the original data from the output. |
An XIntegerViews or XDoubleViews object
if rangesOnly=FALSE.
An IRanges object if rangesOnly=TRUE.
