Due to the limitations of conventional research approaches, we are still far from a comprehensive understanding of mouse placentation, especially regarding the differentiation of trophoblast lineages at the early developmental stage.
pzfx files can only be of type “Column” or “XY”, depending on whether the “X” column is specified by x_col.The placenta is one of the most important yet least understood organs. 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. To accommodate this, NAs are added if the columns are of different lengths. Prism does not require columns in a table to be of the same length. 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.
