The operations currently available are: Aggregation: consolidate data by running different aggregations on columns by a specific index Pivot: this is simple wrapper around pandas.Dataframe.pivot and pandas.pivot_table Transpose: transpose your data on a index (be careful dataframes can get very wide...
layout_by() or the wrapr dot arrow pipe for applying a layout to re-arrange data. t() (transpose/adjoint) to invert or reverse layout specifications. Some convenience functions include: pivot_to_rowrecs(), for moving data from multi-row block records with one value per row (a single co...
We may have to deal with a large amount of CSV, XLXS and other table data in our daily work. However, there are many disadvantages of using traditional CSV editing tools or importing it into database for operations. For example, complex operations cannot be executed through scripts; with low...
NumPy arrays also use much less memory than built-in Python sequences. NumPy operations perform complex computations on entire arrays without the need for Python for loops. To give you an idea of the performance difference, consider a NumPy array of one million integers, and the equivalent ...

Mapping cell type-specific gene expression quantitative trait loci (ct-eQTLs) is a powerful way to investigate the genetic basis of complex traits. A popular method for ct-eQTL mapping is to assess the interaction between the genotype of a genetic locus

where \(\left|\cdot \right|\) stands for the Euclidean norm, T stands for the matrix transpose operation, and Dj ∈ (0, 1) stands for the encoding of the differential expression level of gene vj (see the next subsection for more details). We also discussed the performance of GR...
