Introductory exercises with bioRad
To install the latest bioRad version follow these install instructions
Execute each of the code examples provided below in RStudio, and try to complete the exercises.
# make sure you start with a fresh R session # load the bioRad package library(bioRad) # check the package version packageVersion("bioRad")
##  '0.7.0.9522'
All bioRad’s functions are documented in an extensive function reference online, as well as in manual pages within R:
# bring up the package general help page: ?bioRad
Start by making a new directory on your local machine that you will use for this practical:
# make a new local directory on your machine for this practical # replace the string below with the path of that directory: <- "your/personal/working/directory/" HOME # check that the directory exists. If the next statement evaluates to FALSE, something went wrong: the directory does not exist or you didn't specify its path correctly file.exists(HOME) # we will make HOME our work directory, the default folder in which R will look # for files, and where it will output newly generated files. setwd(HOME) # next, we will create two directories where we will be storing data: dir.create("./data_vpts") # here we will store vertical profile time series (vpts data) dir.create("./data_pvol") # here we will store polar volumes (pvol data) # Finally, we set the local time zone to UTC, so all plotted time axes will be in UTC Sys.setenv(TZ = "UTC")
Next, download the two files posted in the
#biorad channel, and put them in the newly created
Your R session is now properly set up.
