Error installing blotter and quanstrat in debian buster with r version 3.6.1 (in anaconda)

[kmonar]

Hi, I tried below commands but I got an error messages:

install.packages("devtools") require(devtools) install.packages("FinancialInstrument") install.packages("PerformanceAnalytics") install_github("joshuaulrich/xts")

What could be the problem?

Thanks!

Can’t say I recall seeing that error. Try restarting R. If error persists, please send sessionInfo().

Thanks

tar is an essential package in most linux installations, so I am surprised it would not be found.

There are two likely problems. One is that tar is not installed for some reason, in which case you are likely missing other build dependencies as well. The other, simpler answer is that your system is expecting a symbolic link to gtar for some reason.

From a command terminal, try:

which tar

and

which gtar

Normally, there is not a link to /bin/gtar

if which tar returns /bin/tar and which gtar returns nothing, then do

sudo ln -s /bin/tar /bin/gtar

if which tar also returns nothing, then make sure you have all the required build dependencies for R

following these directions:

https://cran.r-project.org/bin/linux/debian/

pay particular attention to adding the repository, and to make sure to install r-base-dev

if tar is still not installed, you can install it via

sudo apt-get install tar

Thanks a lot!

This line you commented 'sudo ln -s /bin/tar /bin/gtar' solved the issue.
