外语不好，谁给看看这话什么意思？ 是要我有100g的内存吗？
Fast aggregation of large data (e.g. 100GB in RAM), fast ordered joins, fast
add/modify/delete of columns by group using no copies at all, list columns,

rocr is better than roc
within obscure several
quantities that are necessary for evaluating the operational
effectiveness of diagnostic tests.
please go to

and

SortableHTMLTables writes a data frame to an HTML file that contains a
sortable table. The sorting is done using the jQuery plugin Tablesorter. The
appearance is controlled through a CSS file and several GIF's.
R对HTML这方面的支持实在是不足，或者说还比较落伍。 |

发帖数: 11290 | 18 I am not sure I totally understand your question. It seems that you need to
find a change point between these two lines and estimate the coefficients p,
q, a,b.
If this is what you want, there are bunch of methods dealing with it. For
example, you can use the segmented regression package to do it; below is the
link for the segmented package using free software R.

it is free and better than Splus
and it is almost the same as Splus but with better management of memory

发帖数: 62 | 24 you probably need to study "Introduction to R":
http://cran.r-project.org/doc/manuals/R-intro.pdf
BTW, you can try following code:
aa=matrix(c(1:4),2,2)
aa
beta<-matrix(0,1,2)
for (k in 1:2){
beta[k]=sum(aa[k,]*sum(aa[,1]*aa[,1]))
}

发帖数: 1123 | 35 We have developed a number of R functions for internal use only (industry
specific).
Is there a way we can build an R package for internal use only (i.e. without
submitting to CRAN)? but internal users can still download zip file and
install it on their R on windows?
Thanks. |

发帖数: 378 | 39 这个叫做Genetic function，我记得好象是S Language里就有定义的吧（具体记不清楚
了），
有一点点类似C++里面的virtual function，根据不同的object类型来调用不同的函数。同样
类似的
函数还有predict，print等等，你看一下源代码，那个NAMESPACE文件，应该有个
S3method的
函数吧，读一下S3method的CRAN手册就应该清楚了。
其实道理很简单，就是让predict对不同的object调用不同的函数，当你的input是一个
lm的
object的时候，predict就变成了predict.lm，当你的object是glm的时候，predict就
变成
了predict.glm，以此类推。因为绝大多数统计模型都需要做预测，利用Genetic
Function就不
再需要根据不同的object来命名预测函数。
R里面这样的函数很多，几乎每一个package都会用到，你可以写一个简单的package实
现一下
default print功能就了解了。 |

发帖数: 100 | 45 请问你使用的是RGtk还是RGtk2？。。4年前不好说，R基本日新月异，Michael他们在写
一本R中GUI
开发的新书，explorase使用RGtk2，不是gWidgets开发的，是比较好的典范。当然可以
用其他语言
写，但是现在的Gtk和Qt的API基本是全功能的了，而且源于R的便于开发R里面的GUI，
保持了代码的
一致。
把他跟perl比，比把他跟SAS比合适多了。perl开源，脚本语言，有cpan，R开源免费，
脚本语言，免
费，有cran，而且他的交互式的操作又和python挺像的。这些语言语法上都和c类似，
都可以面向对象
的编程。而且R，perl,python很多时候都是粘合性的语言，粘合C，java，C++或者其他
其他语言。
易用性是脚本语言的特点。固然，perl跟python用户群非常之大，也许这么比较他们不
大乐意，但是
从语言的角度上，设计角度上，这种相似不能否认啊啊 |
