LongDat R package takes longitudinal dataset as input data and analyzes if there is significant change of the features over time (proxy for treatments), while detects and controls for covariates at the same time. LongDat is able to take in several data types as input, including count, proportion, binary, ordinal and continuous data. The output table contains p values, effect sizes and covariates of each feature, making the downstream analysis easy.
Install LongDat by typing install.packages("LongDat") in
R.
If you encounter errors like the one below when installing the
package
Error: package or namespace load failed for ‘LongDat’ object ‘A’ is not exported by 'namespace:B_package'
please try install the dependency B_package first, and then try to
install LongDat again. An example to this kind of problem and solution
can be found here
Tutorials for the analysis on continuous time variable (e.g. days) can be found here.
Tutorials for the analysis on discrete time variable (e.g. before/after treatment) can be found here.
Alternatively, you can type browseVignettes(“LongDat”)
in R after installing LongDat to access these tutorials.
