rAmCharts (version 1.1.1)

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)
## S3 method for class 'data.frame':
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)
library(data.table)
start <- as.POSIXct("01-01-2015", format = "%d-%m-%Y")
end <- as.POSIXct("31-12-2015", format = "%d-%m-%Y")
period <- seq.POSIXt(from = start, to = end, by = "10 min")
n <- length(period)
periodTemp <- seq.POSIXt(from = start, to = end, by = "3 hour")
nTemp <- length(periodTemp)
### Generate mesures ----
charge <- rnorm(n, mean = 500, sd= 200)
charge[ which(charge < 0) ] <- rnorm(length(which(charge < 0)), mean = 200, sd = 10)
temp <- rnorm(nTemp, mean = 15, sd = 10)
dtCharge <- data.table::data.table(charge, date = period)
setkey(dtCharge, date)
dtTemp <- data.table::data.table(temperature = temp, date = periodTemp)
setkey(dtTemp , date)
dp <- dtTemp[dtCharge]
dp[ , date := format(date, "%m-%d-%Y %H:%M:%S")]
toList(dp[1:10, ], keepNA = FALSE)
