在我试图找到解决其他问题的方法时,我感到很沮丧,只是用library(lattice)
library(gridExtra) # for grid.arrange()
p1 <- levelplot(t(apply(matrix(newdat[,1], 2, 4, byrow=TRUE), 1, rev)))
p2 <- levelplot(t(apply(matrix(newdat[,2], 2, 4, byrow=TRUE), 1, rev)))
p3 <- levelplot(t(apply(matrix(newdat[,3], 2, 4, byrow=TRUE), 1, rev)))
grid.arrange(p1, p2, p3, ncol=3)
# Or in a loop:
p <- apply(newdat, 2, function(i) levelplot(t(apply(matrix(i, 2, 4, byrow=TRUE), 1, rev))))
grid.arrange(p[[1]], p[[2]], p[[3]], ncol=length(p))
删除了我的Ruby安装。用rm -rf ~/.rbenv/versions/2.2.2
重新安装后,我发现突然间我无法安装rbenv install 2.2.2
宝石。 bundler
命令导致以下错误:
gem install bundler
我读过的所有内容似乎表明缺少ERROR: Loading command: install (LoadError)
cannot load such file -- zlib
ERROR: While executing gem ... (NoMethodError)
undefined method `invoke_with_build_args' for nil:NilClass
包通常是Linux系统的问题。但是,我正在使用OSX 10.10.4并且我已经读过zlib
应该带有命令行工具,我有。
经过一堆谷歌搜索并没有进展后,我决定重新开始使用rbenv。我卸载了rbenv并重新安装了它,但我仍然无法使用我的rbenv安装ruby 2.2.2安装bundler。更重要的是,我发现我根本无法安装版本2.2.0或2.2.1:
zlib
我完全没有想法,如果有人认为他们可能知道发生了什么,我会感激任何帮助。在这一点上,我的开发环境几乎完全被淹没了。

答案 0 :(得分:0)
事实证明,a)我的Xcode安装发生了什么(不确定它会发生什么/怎么发生)或b)升级OSX后升级后需要手动更新Xcode。
即使我升级了命令行工具,我决定在App Store中检查我的Xcode安装,并注意到可以安装/更新。所以我做到了,然后一切正常。
