The package was developed for Rotated Combination of Two-Component (RCTC) Ground Motions calculation. Please refer to the PEER report for some detail.

1. Make sure “Rcpp” and “pracma” are installed as they are dependencies. Otherwise, you can run the following command to install them.

install.packages(c('Rcpp', 'pracma'))

2. For Mac users, you may need to download Xcode for command line tools or (by running the following command in Terminal):

xcode-select --install

For Windows users: you may need to download and install Rtools (and remember to add path into the system environment path when installing):

3. Install utility pacakge “devtools”:

install.packages("devtools")

4. Lastly, install “RCTC” pacakge:

library(devtools)
install_github('wltcwpf/RCTC')

If you use RCTC (directly or as a dependency of another package) for work resulting in an academic publication, we would appreciate if the report is cited:
