Exploratory Data Analysis Using R provides a classroom-tested introduction to exploratory data analysis (EDA) and introduces the range of "interesting" – good, bad, and ugly – features that can be found in data, and why it is important to find them. It also introduces the mechanics of using R to explore and explain data. The book begins with a detailed overview of data, exploratory analysis, and R, as well as graphics in R. It then explores working with external data, linear regression models, and crafting data stories. The second part of the book focuses on developing R programs, including good programming practices and examples, working with text data, and general predictive models. The book ends with a chapter on "keeping it all together" that includes managing the R installation, managing files, documenting, and an introduction to reproducible computing. The book is designed for both advanced undergraduate, entry-level graduate students, and working professionals with little to no prior exposure to data analysis, modeling, statistics, or programming. it keeps the treatment relatively non-mathematical, even though data analysis is an inherently mathematical subject. Exercises are included at the end of most chapters, and an instructor's solution manual is available. About the Author: Ronald K. Pearson holds the position of Senior Data Scientist with GeoVera, a property insurance company in Fairfield, California, and he has previously held similar positions in a variety of application areas, including software development, drug safety data analysis, and the analysis of industrial process data. He holds a PhD in Electrical Engineering and Computer Science from the Massachusetts Institute of Technology and has published conference and journal papers on topics ranging from nonlinear dynamic model structure selection to the problems of disguised missing data in predictive modeling. Dr. Pearson has authored or co-authored books including Exploring Data in Engineeri

SX1276是一款广泛应用在LoRa无线通信技术中的射频收发器,由Semtech公司制造。LoRa(Long Range)是一种远距离、低功耗的无线通信技术,广泛用于物联网(IoT)设备。在给定的压缩包文件"sx1276.zip"中,包含了使用SX1276进行串口透明传输的相关资料,适用于基于STM32F103ZET6微控制器的项目。 STM32F103ZET6是意法半导体(STMicroelectronics)推出的高性能ARM Cortex-M3内核MCU,具有丰富的外设接口,包括SPI,适用于驱动SX1276这样的射频芯片。在硬件SPI接口下,STM32能够高效地与SX1276交互,实现高速数据传输。 描述中提到的"FSK连续模式透传代码"是指使用频率移键控(Frequency Shift Keying)调制方式,这是一种常见的数字调制技术,通过改变载波频率来表示二进制数据。在连续模式下,信号会一直保持活动状态,直到有停止命令为止,这对于保持无线连接的稳定性非常重要。 串口透明传输是一种通信协议,使得任何通过串口发送的数据都能原封不动地通过无线链路到达接收端,这为用户提供了极大的便利,无需关心底层通信协议,只需要处理应用层的数据。 压缩包内的文件结构如下: 1. "keilkill.bat":这可能是一个批处理文件,用于清理或关闭Keil μVision IDE,Keil是常用的STM32开发环境。 2. "readme.txt":通常包含项目的基本说明、使用指南或注意事项。 3. "Tan"、"Project"、"User":这些可能是工程文件夹,分别包含项目的配置、用户设置等信息。 4. "Doc":文档文件夹,可能包含硬件接线图、用户手册、技术规格等详细资料。 5. "Libraries":库文件夹,可能包含与SX1276和STM32相关的驱动库和函数。 为了使用这个项目,你需要: 1. 首先解压sx1276.zip,获取所有文件。 2. 执行"keilkill.bat",确保开发环境准备就绪。 3. 查阅"readme.txt"了解项目详情和操作步骤。 4. 在Keil μVision中打开"Project"文件夹下的工程,并导入"Libraries"中的库文件。 5. 根据"Doc"中的接线图正确连接STM32F103ZET6和SX1276模块。 6. 编译并下载代码到STM32,确保硬件SPI接口以及FSK模式配置正确。 7. 测试串口透明传输功能,确保发送和接收数据的一致性。 通过这个项目,你可以学习到如何使用STM32与射频芯片进行通信,理解LoRa和FSK调制的工作原理,以及如何实现在物联网设备间的串口透明传输。这将对你的嵌入式系统开发技能有显著提升。
