Hello R-Help People! I had to reinstall my operating system... and reinstall R. I am having trouble with reinstalling packages: install.packages(c( "curl")) install.packages(c( "quantmod")) install.packages(c( "TTR")) install.packages(c( "xts")) install.packages(c( "zoo")) install.packages(c( "tidyquant"))install.packages(c( "TTR")) Some of these install with no problem. However, most of them give an error messages that looks like: Warning in install.packages : installation of package ?curl? had non-zero exit status There seems to be some sort of content for each of these packages (and others) in my /tmp/RtmpiTrqk2/downloaded_packages/ directory. Whey I try to load these packages with library(curl) library(xts) library(zoo) library(quantmod) library(TTR) library(tidyquant) I get a message like this one: Error in library(quantmod) : there is no package called ?quantmod? How do I install and load these packages successfully? Thank you! Phil Smith Sent with [Proton Mail](https://proton.me/) secure email. [[alternative HTML version deleted]]

Scroll up to see the error messages produced when installing the curl package. You'll see that it's complaining about the lack of development headers for cURL library. If you install them using your package manager (which could be `sudo apt install libcurl4-openssl-dev`, `sudo yum install curl-devel` or something else depending on the OS/distro), the installation of the curl package should succeed, allowing you to install other packages that depend on it. -- Best regards, Ivan
