Average protein intensities over technical replicates

Average protein intensities over technical replicates

average_technical_replicates(df, cond, log = TRUE)

Arguments

df	A data frame of protein intensities
cond	A data frame containing the description of df's columns (i.e "bckg", "time", "bio" and "tech") as returned by function identify_conditions()
log	use geometric mean

Value

A list containing :

Intensity, a data frame of protein intensities averaged over technical replicates;

conditions, a data frame containing the description of Intensity's columns

Examples

#load data :
data("proteinGroups_Cbl")
df <- proteinGroups_Cbl
cond <- identify_conditions(df)
Column_intensity_pattern <- "^Intensity."
df_int <- df[ , grep(Column_intensity_pattern, colnames(df))]
avg <- average_technical_replicates(df_int, cond)
