Я попытался установить два пакета в R Studio: tidyverse и quantmod. Однако оба дают мне ошибки, и я не могу понять, почему (поиск в Google не помогает понять проблему).
За аккуратный стих я получаю:
> install.packages("tidyverse")
also installing the dependency ‘xml2’
There are binary versions available but the source versions are later:
binary source needs_compilation
xml2 1.1.1 1.2.0 TRUE
tidyverse 1.1.1 1.2.1 FALSE
Do you want to install from sources the package which needs compilation?
y/n: y

------------------------- ANTICONF ERROR ---------------------------
Configuration failed because libxml-2.0 was not found. Try installing:
* deb: libxml2-dev (Debian, Ubuntu, etc)
* rpm: libxml2-devel (Fedora, CentOS, RHEL)
* csw: libxml2_dev (Solaris)
If libxml-2.0 is already installed, check that 'pkg-config' is in your
PATH and PKG_CONFIG_PATH contains a libxml-2.0.pc file. If pkg-config
is unavailable you can set INCLUDE_DIR and LIB_DIR manually via:
R CMD INSTALL --configure-vars='INCLUDE_DIR=... LIB_DIR=...'

Я думаю, что это может иметь отношение к моему пути, но я не достаточно опытен, чтобы заставить его работать.
