将命名字符向量转换为 data.frame [英] Convert Named Character Vector to data.frame

问题描述

我有一个从 xmlAttrs 返回的命名字符向量，如下所示:

I have a named character vector returned from xmlAttrs like this:

testVect <- structure(c("11.2.0.3.0", "12.89", "12.71"), .Names = c("db_version", 
             "elapsed_time", "cpu_time"))

我想将其转换为如下所示的数据框:

I would like to convert it to a data frame that looks like this:

testDF <- data.frame("db_version"="11.2.0.3.0","elapsed_time"=12.89,"cpu_time"=12.71)
head(testDF)
  db_version elapsed_time cpu_time
1 11.2.0.3.0        12.89    12.71

推荐答案

就像 data.frame(as.list(testVect)) 一样简单.或者，如果您想要列的合理数据类型，data.frame(lapply(testVect, type.convert), stringsAsFactors=FALSE).

It's as simple as data.frame(as.list(testVect)). Or if you want sensible data types for your columns, data.frame(lapply(testVect, type.convert), stringsAsFactors=FALSE).
