pzfx files can only be of type “Column” or “XY”, depending on whether the “X” column is specified by x_col.

When reading into R, column names with special formating are converted to regular strings.įor writing, because R data frames and matrices don’t support hierachical columns, the written out. Prism allows special formating of column names such as superscripts. Note if strike_action='star' the entire table is converted to type character. One can choose to delete these values with strike_action='exclude', keep them with 'keep', or convert them to a trailing '*' (as they appear in Prism) with 'star'. To accommodate this, an option strike_action is available in read_pzfx. Prism allows user to exclude data by striking them out individual observations.

Without normalization, plotting raw data onto a heat map can make it difficult to interp. Prism does not require columns in a table to be of the same length. In this video tutorial, I will show you how to normalize a heat map. For example, trailing _MEAN, _SD, _N are added if subcolumns represent mean, standard deviation and number of observations. It tries to infer the subcolumn types and adds appropriate suffix accordingly. To accommodate this, read_pzfx automatically adds _1, _2 etc to the original column name to account for sub columns if they represent replicates.
