描述----------Description----------
Generic functions to extract genomic features from an object. This page documents the methods for TranscriptDb objects only.
从对象中提取的基因组功能的通用功能。这个页文件只TranscriptDb对象的方法。
用法----------Usage----------
transcripts(x, ...)
## S4 method for signature 'TranscriptDb'
transcripts(x, vals=NULL, columns=c("tx_id", "tx_name"))
exons(x, ...)
## S4 method for signature 'TranscriptDb'
exons(x, vals=NULL, columns="exon_id")
cds(x, ...)
## S4 method for signature 'TranscriptDb'
cds(x, vals=NULL, columns="cds_id")
参数----------Arguments----------
参数:x
A TranscriptDb object.
TranscriptDb对象。
参数:...
Arguments to be passed to or from methods.
参数被传递到或从方法。
参数:vals
Either NULL or a named list of vectors to be used to restrict the output. Valid names for this list are: "gene_id", "tx_id", "tx_name", "tx_chrom", "tx_strand", "exon_id", "exon_name", "exon_chrom", "exon_strand", "cds_id", "cds_name", "cds_chrom", "cds_strand" and "exon_rank".
要么NULL或一个被用来限制输出的向量命名名单。这个名单中的有效的名字是:"gene_id","tx_id","tx_name","tx_chrom","tx_strand","exon_id","exon_name", "exon_chrom","exon_strand","cds_id","cds_name","cds_chrom","cds_strand"和"exon_rank"。
参数:columns
Columns to include in the output. Must be NULL or a character vector with values in the above list of valid names. With the following restrictions:
在输出中包括列。必须NULL或以上的有效名称列表中的值与特征向量。具有下列限制:
"tx_chrom" and "tx_strand" are not allowed for transcripts.
"tx_chrom"和"tx_strand"不transcripts允许的。
"exon_chrom" and "exon_strand" are not allowed for exons.
"exon_chrom"和"exon_strand"不exons允许的。
"cds_chrom" and "cds_strand" are not allowed for cds.
"cds_chrom"和"cds_strand"不cds允许的。
Details
详情----------Details----------
These are the main functions for extracting transcript information from a TranscriptDb object. They can restrict the output based on categorical information. To restrict the output based on interval information, use the transcriptsByOverlaps, exonsByOverlaps, and cdsByOverlaps functions.
这些成绩单从TranscriptDb对象信息提取的主要职能。他们可以限制基于分类信息的输出。要限制基于间隔的信息输出,使用transcriptsByOverlaps,exonsByOverlaps,cdsByOverlaps功能。
值----------Value----------
a GRanges object
1农庄对象

举例----------Examples----------
txdb <- loadFeatures(system.file("extdata", "UCSC_knownGene_sample.sqlite",
package="GenomicFeatures"))
vals <- list(tx_chrom = c("chr3", "chr5"), tx_strand = "+")
transcripts(txdb, vals)
exons(txdb, vals=list(exon_id=1), columns=c("exon_id", "tx_name"))
exons(txdb, vals=list(tx_name="uc009vip.1"), columns=c("exon_id", "tx_name"))
