如何将 !duplicate 与 rpy2 一起使用？

我想做与此 R 脚本等效的操作：

> csvData <- read.csv(file='/homes/ndeklein/test.csv', head=TRUE, sep='\t')
> csv = subset(csvData, !duplicated(id))

在 rpy2 中。但是，如果我将 rpy2.robjects 导入为 R，它无法识别 Rr['!duplicated'] （像这样）：

import rpy2.robjects as R
csvData = R.r['read.csv'](file='/homes/ndeklein/test.csv', head=True, sep='\t')
csv = R.r['subset'](csvData, R.r['!duplicated']('id'))

如何在 rpy2 中使用 !duplicated？

编辑：

R.r['duplicated']

确实有效，所以我正在寻找如何制作！在 rpy2 中工作

I want to do the equivalent of this R script:

> csvData <- read.csv(file='/homes/ndeklein/test.csv', head=TRUE, sep='\t')
> csv = subset(csvData, !duplicated(id))

in rpy2. However, if I import rpy2.robjects as R, it does not recognize R.r['!duplicated']
(like this):

import rpy2.robjects as R
csvData = R.r['read.csv'](file='/homes/ndeklein/test.csv', head=True, sep='\t')
csv = R.r['subset'](csvData, R.r['!duplicated']('id'))

How can I use !duplicated in rpy2?

edit:

R.r['duplicated']

does work, so I'm looking for how to make ! work in rpy2

我通过邮件列表得到了答案，以防其他人需要它：

使用 Rr'!'而不是 Rr'！重复的'作品。

# getting the not sign of R
rnot = R.r['!']
# getting duplicated
duplicated = R.r['duplicated']
# get only the rows with unique ids and put it in a new matrix
csvUniqID = R.r['subset'](csvData,  rnot(duplicated(csvData[0])))

I got the answer trough a mailing list, in case someone else needs it:

Using R.r'!' instead of R.r'!duplicated' works.

# getting the not sign of R
rnot = R.r['!']
# getting duplicated
duplicated = R.r['duplicated']
# get only the rows with unique ids and put it in a new matrix
csvUniqID = R.r['subset'](csvData,  rnot(duplicated(csvData[0])))
