Command history in R

阅读更多关于 Command history in R

问题 Is there any IDE -from the ones supporting R-, that gives access to the command history (at least to the current session's commands)? Or is there a way to get a (character or expression) vector with those commands in R? For those of you that have been using MATLAB, I mean something like the Command History window there.. Thank you 回答1: history(Inf) opens a window similar to that in MATLAB. 回答2: savehistory('file') myhistory <- scan('file','character') Might do the trick. 回答3: I would highly

How to set Eclipse watchpoint to activate when object/primitive changes?

阅读更多关于 How to set Eclipse watchpoint to activate when object/primitive changes?

I'm trying to refactor some rather horrible code at the moment. It's passing around objects in a very convoluted manner I can't keep track of and apparently directly accessing primitives within the objects at some other location in the code. I'm trying to figure out how I can use the debugger to find out when/where an object I'm interested in is used after it gets passed into the confusing black box of code which passes these objects. What I would like is a way to set a watchpoints that breaks when an Object (or primitive) is modified. I know that watchpoints can be set on variables, but this

阅读更多关于 Eclipse: How to share Java compiler errors/warnings settings across entire team

问题 We are in the process of standardizing our default Eclipse configuration (styles, settings, dictionary, formatting, run configurations, etc.) for our developers. However, for Java compiler errors and warnings preferences, there does not seem to be any way to export/import settings. Is there another way to do this? 回答1: The ideal way to share settings within the team (for use within the IDE) is to use project specific settings . The project specific settings become part of the project and go

阅读更多关于 Webstorm: how to extend to handle PHP files or even just highlight code correctly?

问题 I tried this IDE and I like it. Only problem is that if Im in a project that has some PHP in it, its confusing to see plain black text instead of correct PHP highlight. I dont need brutal PHP autocomplete or so, but a syntax highlight. Is it possible to achieve in Webstorm? Or the only option is to use PHPStorm? 回答1: UPDATE : since TextMate bundles support was added to the IDE, you can add any language syntax highlighting to the IDE if there is TextMate bundle for it. See my reply about

Can I use a RAM disk to speed up my IDE?

阅读更多关于 Can I use a RAM disk to speed up my IDE?

问题 Duplicate: RAMDrive for compiling - is there such a thing? I have an idea how to speed up my IDE. I want to create a RAM disk and move my solution onto this virtual disk.

Am
