每次我更新都R
必须发生一些事情......无论如何,这一次(显然只适用于data.table
,其他类似的包装ggplot2
以及所有由它导入的包装都很好)我得到了这个:
> library("data.table", lib.loc="C:/Program Files/R/R-3.0.2/library")
data.table 1.8.10 For help type: help("data.table")
> detach("package:data.table", unload=TRUE)

卸载软件包并使用 Rtools 从源重新安装时,输出完全相同。他们只是warnings
我知道,但我很好奇/有点担心这是否会在以后暗示其他事情。
编辑:Rcpp
同样(30个警告)和不同的data.table
是,Rpcc
不起作用:
> evalCpp('2 * M_PI')
Error in sourceCpp(code = code, env = env, rebuild = rebuild, showOutput = showOutput, :
SET_VECTOR_ELT() can only be applied to a 'list', not a 'symbol'
