我将其下载到我的C驱动器在这个位置C:/ CDA驱动器作为popular.tsv
我正在尝试读入数据帧。我使用源和负载,我在这两个中都有错误。
> present = source(C://CDA//popular.tsv)
源错误(C://CDA//popular.tsv):
C://CDA//popular.tsv:1:9:意外符号
1:性别等级
^
>现在=加载(C://CDA//popular.tsv)
错误:坏的恢复文件魔术数字(文件可能已损坏) - 无数据加载
另外:警告消息:
文件'popular.tsv'有魔术数字'gende'
使用2之前的保存版本已被弃用
> present = read.table(C:// CDA //popular.tsv)
扫描错误(文件,什么,nmax,sep,dec,quote,skip,nlines,na.strings,
第23行没有11个元素
请帮忙!
谢谢
您正在使用错误的函数来读取数据。
加载
是用于使用R保存的对象保存的数据文件(通常以.Rdata或.rda结尾的文件)。 source
通常用于读取文件或连接包含R脚本。
您应该尝试 read.table
和family。由于这是一个标签分隔文件,您可以使用:
r ead.delim(C://CDA//popular.tsv)
## ^^与`read.table(...,header = TRUE,sep =\t)相同)
## see?read.table了解更多详情
Hi I am trying to load a dataset that I downloaded from this link: https://docs.google.com/spreadsheet/ccc?key=0AkY2lFgS9uiDdDdxazdLMnUwalpyMjc0UlY1U2p4cnc#gid=0
I downloaded it into my C drive in this location C:/CDA drive as popular.tsv
I am trying to read it into a dataframe. I use both source and load and I get an error in both of them.
>present=source("C://CDA//popular.tsv")
Error in source("C://CDA//popular.tsv") :
C://CDA//popular.tsv:1:9: unexpected symbol
1: gender grade
^
> present=load("C://CDA//popular.tsv")
Error: bad restore file magic number (file may be corrupted) -- no data loaded
In addition: Warning message:
file ‘popular.tsv’ has magic number 'gende'
Use of save versions prior to 2 is deprecated
>present=read.table("C://CDA//popular.tsv")
Error in scan(file, what, nmax, sep, dec, quote, skip, nlines, na.strings, :
line 23 did not have 11 elements
Please help! Thanks
You are using the wrong functions to read the data in.
load
is for data files which have been saved using R's saved objects (usually files ending with ".Rdata" or ".rda"). source
is generally used to read files or connections containing R scripts.
You should try read.table
and family. Since this is a tab separated file, you can use:
read.delim("C://CDA//popular.tsv")
## ^^ is the same as `read.table(..., header = TRUE, sep = "\t")
## see ?read.table for more details
