rAmCharts (version 1.1.2)

toList: Convert a data.frame in list

Description

This function is useful for the use of rAmChart, particularly for drill-down feature

Usage

toList(df, keepNA = TRUE)
"toList"(df, keepNA = TRUE)

Arguments

df

data.frame containing the data.

keepNA

logical.

Details

Each row of the data.frame will be transform into a named list. Consequently, be sure that the columns are correctly named.

Examples

toList(data.frame(V1 = c(rep(NA, 5), 6:10), V2 = 11:20, Char = rep("test", 10)), keepNA = FALSE)
