Read and Write 'GraphPad Prism' Files.

pzfx

Read GraphPad Prism .pzfx files into R. It tries to understand different .pzfx table formats, e.g. replicates as subcolumns, or mean-sd-n as subcolumns etc and adds proper suffix to column names of the parsed output.

Installation

# Install from CRAN
install.packages("pzfx")

# Install development version from GitHub
devtools::install_github("Yue-Jiang/pzfx")

Usage

To list tables in a .pzfx file

library(pzfx)
pzfx_tables("/path/to/my/pzfx/file")

To read a specific table from a .pzfx file

df <- read_pzfx("/path/to/my/pzfx/file", 1) # read first table
df <- read_pzfx("/path/to/my/pzfx/file", "Table Name") # read table by name

To write a data frame or matrix to a .pzfx file

write_pzfx(df, "/path/to/my/pzfx/file")

To write a list of data frames or matrices to a .pzfx file

write_pzfx(list("Table Name 1" = df1, "Table Name 2" = df2), "/path/to/my/pzfx/file")

Note

A few years after this package was first released, GraphPad has introduced a new file format .prism and is more open. If you are interested in working with the new format in R, please check out the prism2R package by Miha Kosmac.
