I know I can print a function by typing its name at the prompt: > t function (x) UseMethod("t") In this case, what does UseMethod("t") mean? How do I find the source code that's actually being used by, for example: t(1:10) ? In other cases, I can see that R functions are being called, but I can't find the source code for those functions. > ts.union function (..., dframe = FALSE) .cbind.ts(list(...), .makeNamesTs(...), dframe = dframe, union = TRUE) > .cbindts Error: object

Is it possible to create a C varargs function with no arguments? For example: int foo(...); I want to do something like the following: list* create_list(...){ list *mylist = list_create(); void *current_arg = va_arg(void*); while (current_arg != NULL){ list_add(mylist, current_arg); current_arg = va_arg(void*); } return mylist; } 回答1: No. Variadic functions must have one or more named parameters. Try it yourself, you'll see something like:

The response variable medv is to be “regressed” against the remaining nine attributes. I have done it as below: f <- medv ~ crim + indus + nox + rm + age + dis + tax + ptratio + lstat To set up train sample 400 of the 506 rows of

What I need is to grab all data value in uppercase. 回答1: The value returned from this $(this).data('value') is of the type number . I.e: console.log(typeof $(this).data('value')); You first

Each file has different number of columns but the records share the same nature: keyed on a date string and all the rest of the columns are float numbers. I need to do some statistical calculation on the float format data columns before persist the results into the database. Although I got all the plumbing logic working: read in the CSV via FSharp.Data CSV type provider, use reflection to get the type of the each column fields together with the

由于工作中需要用到rtp协议，java暂时没有比较好的开发框架，参考了其他的一些博文，自己摸索着使用jrtplib库，在此记录一下。 关于如何编译jrtplib库，在我的上一篇有讲解 jrtplib库移植到android上 可根据自身需求，参考实现的功能。 实现的功能 一、接收端 接收RTP数据，携带数据并回调通知Java端； 接收RTCP、BYE等数据，携带数据发送端IP字符串并回调通知Java端； 实现网络摄像机RTSP协议对接； 实现接收RTP数据，并转发RTP数据。 二、发送端 1、实现H264编码数据分包发送； 2、发送RTP数据； 3、接收RTCP、BYE等数据，并携带数据发送端IP字符串回调至Java。 准备工作 Android.mk 文件编写 LOCAL_PATH := $ ( call my - dir ) include $ ( CLEAR_VARS ) LOCAL_MODULE := jthread LOCAL_SRC_FILES := libjthread . a include $ ( PREBUILT_STATIC_LIBRARY ) include $ ( CLEAR_VARS ) LOCAL_MODULE := jrtp LOCAL_SRC_FILES := libjrtplib . a LOCAL_STATIC_LIBRARIES :=
