Determination of amino acids and analysis of the volatile oil in seeds of Chelidonium majus by reversed phase high-performance liquid chromatography. Objective To investigate the volatile oil in seeds of Chelidonium majus and determinate the content of 21 free and hydrolyzed amino acids in the ...
Basic correlation matrix heatmap Use the arguments k_col and k_row to specify the desired number of groups by which to color the dendrogram’s branches in the columns and rows, respectively. heatmaply_cor( cor(df), xlab = "Features", ylab = "Features", k_col = 2, k_row = 2 ) ...

Illustrates how the data matrix is “unboxed” and embedded into the hierarchical clustering of a symmetric matrix. The process is similar for asymmetric matrices, except there are no redundant cells to remove. Top Left: A standard cluster heatmap of a correlation matrix. Top Middle: The ...
We’ll use the functions below to set half of it to NA. Helper functions : # Get lower triangle of the correlation matrix get_lower_tri<-function(cormat){ cormat[upper.tri(cormat)] <- NA return(cormat) } # Get upper triangle of the correlation matrix get_upper_tri <- func...
