我尝试使用以下命令安装devtool包
install.packages('devtools')
我得到以下输出:
ERROR: dependency âxml2â is not available for package ârversionsâ

我正在尝试在Ubuntu14.04上安装R 3.0.2 devtools包,如下所示:

请看下面的代码。对于某些链接,这将导致R执行核心转储。我刚刚添加了一个示例链接,这可能有助于调试。

在过去的几天里,我一直在努力让RStudio打开或关闭,最终让它运行起来,并开始安装包。Readr安装得很好,但tidyverse拒绝安装。 /usr/bin/ld: /usr/local/lib/libcrypto.a(v3_genn.o): relocation R_X86_64_PC32 against symbol `GENERAL_NAME_it' can not be used when making a shared object; recompile with -fPIC

在R中使用xml2包将HTML实体转换为Unicode字符:
xml2::read_html("<html> This is a dash – <html>")
# {xml_document}
# <html>
# [1] <body><p> This is a dash \u2013 </p></body>
我希望保留HTML实体,因为如果我后来使用pandoc将HTML转换为LaTeX,\u2013将被删除,而–将正确地转换为--。
我如何才能做
我试图通过install.packages("devtools")在Rstudio中安装devtools包,但是失败了。错误消息包括:

我试图在R Studio中安装两个软件包: tidyverse和quantmod。然而,这两种方法都会给我带来错误,我也不明白为什么(googling并不能帮助我理解问题)。
