AnnDbBimap-envirAPI {AnnotationDbi} | R Documentation |
These methods allow the user to manipulate any AnnDbBimap object as if it was an environment. This environment-like API is provided for backward compatibility with the traditional environment-based maps.
ls(name, pos, envir, all.names, pattern) exists(x, where, envir, frame, mode, inherits) get(x, pos, envir, mode, inherits) #x[[i]] #x$name ## Converting to a list mget(x, envir, mode, ifnotfound, inherits) eapply(env, FUN, ..., all.names, USE.NAMES) #contents(object, all.names) ## Additional convenience method sample(x, size, replace=FALSE, prob=NULL, ...)
name |
An AnnDbBimap object for ls .
A key as a literal character string or a name (possibly backtick quoted)
for x$name .
|
pos |
Ignored. |
envir |
Ignored for ls . An AnnDbBimap object for mget ,
get and exists .
|
all.names |
Ignored. |
USE.NAMES |
Ignored. |
pattern |
An optional regular expression. Only keys matching 'pattern' are returned. |
x |
The key(s) to search for for exists , get and mget .
An AnnDbBimap object for [[ and x$name .
An AnnDbBimap object or an environment for sample .
|
where |
Ignored. |
frame |
Ignored. |
mode |
Ignored. |
inherits |
Ignored. |
i |
Single key specifying the map element to extract. |
ifnotfound |
A value to be used if the key is not found. Only NA is currently
supported.
|
env |
An AnnDbBimap object. |
FUN |
The function to be applied (see original eapply
for environments for the details).
|
... |
Optional arguments to FUN .
|
size |
Non-negative integer giving the number of map elements to choose. |
replace |
Should sampling be with replacement? |
prob |
A vector of probability weights for obtaining the elements of the map being sampled. |
