无法安装R包的最新版本

Question

I am interested in using ClickStream R package, particularly version 1.3.0. I have installed it with:

install.packages("clickstream")

However, the version that was downloaded is 1.1.9, which is missing several important functions. I have tried to updated the package within R-studio using Tools -> Check for Package Updates , but it says all packages are up to date. The version of R-studio is 1.1.453.

I just cannot figure out what I am supposed to do to automatically download the latest version of this package. Any help?

You are probably attempting to install from a repository that is out-of-date. Going to the CRAN page for clickstream we see that it has version 1.3.0 for all the major branches of R. There was a time when installing RStudio resulted in getting an out-of-date version of R, which then required that one install an up-to-date version of R. I think they also had a "matching" repo for that version so you wouldn't get a warning message:

# Check your R version
R.version$version.string
#[1] "R version 3.5.1 (2018-07-02)"          #result if all is well

URL for CRAN page
https://cran.r-project.org/web/packages/clickstream/index.html

It has several dependencies:

Depends:    R (≥ 3.0.1), methods, igraph, stats, utils, reshape2, data.table, MASS
Imports:    plyr, Rsolnp, arules, linprog, ggplot2, ClickClust, parallel

You can figure out where you are getting packages with:

options()$repos
