R的新手。最近通过ATAC-seq workshow in R工作。
在我调用makeGRangesFromDataFrame函数的5.1节中，出现以下错误-
> atac_esca.gr <- makeGRangesFromDataFrame(atac_esca,keep.extra.columns = T)
Error in makeGRangesFromDataFrame(atac_esca, keep.extra.columns = T) : could not find function "makeGRangesFromDataFrame"
我以前安装了GenomicRanges软件包，然后再次尝试。不开心所以我附上了包裹require(GenomicRanges)现在当我重复以下通话时收到以下错误-
> atac_esca.gr <- makeGRangesFromDataFrame(atac_esca,keep.extra.columns = T)
Error in inherits(object, class2) : 'what' must be a character vector
[[Edit]：dput results
> dput(head(atac_esca,10))

有人可以告诉我我在做什么错吗？
[[使用R Studio 1.2.5033-R 3.6.3-Windows 10]
谢谢，

您有小题词，并且功能makeGRangesFromDataFrame与data.frame一起使用。处理多余的列时会引发一些问题：
str(atac_esca)
Classes ‘spec_tbl_df’, ‘tbl_df’, ‘tbl’ and 'data.frame': 10 obs. of 8 variables:
$ seqnames : chr "chr1" "chr1" "chr1" "chr1" ...
$ start : num 1290095 1291115 1291753 1440824 1630188 ...
$ end : num 1290596 1291616 1292254 1441325 1630689 ...
$ name : chr "ESCA_107" "ESCA_108" "ESCA_109" "ESCA_160" ...
$ score : num 2.46 2.59 7.58 4.47 20.62 ...
$ annotation: chr "3' UTR" "3' UTR" "3' UTR" "3' UTR" ...
$ percentGC : num 0.677 0.703 0.639 0.659 0.729 ...
$ percentAT : num 0.323 0.297 0.361 0.341 0.271 ...
- attr(*, "spec")=List of 3
..$ cols :List of 8
.. ..$ seqnames : list()
.. .. ..- attr(*, "class")= chr "collector_character" "collector"
.. ..$ start : list()
.. .. ..- attr(*, "class")= chr "collector_double" "collector"
此作品：
makeGRangesFromDataFrame(atac_esca)
GRanges object with 10 ranges and 0 metadata columns:
seqnames ranges strand
<Rle> <IRanges> <Rle>
[1] chr1 1290095-1290596 *
[2] chr1 1291115-1291616 *
[3] chr1 1291753-1292254 *
要保留其他列，您需要转换为data.frame：
makeGRangesFromDataFrame(as.data.frame(atac_esca),keep.extra.columns = TRUE)
GRanges object with 10 ranges and 5 metadata columns:
seqnames ranges strand | name score
<Rle> <IRanges> <Rle> | <character> <numeric>
[1] chr1 1290095-1290596 * | ESCA_107 2.46437811814343
[2] chr1 1291115-1291616 * | ESCA_108 2.58792851900195
[3] chr1 1291753-1292254 * | ESCA_109 7.57996223017863
[4] chr1 1440824-1441325 * | ESCA_160 4.46727398384637
