Visualize time trends of nutrient intake levels

Description

This function allows visualizing time trends of intake levels of one or several nutrients.

Usage

nutrientsTimeTrend(my_daily_food, food_database = "USDA", nutrients = NULL,
                   age = 27, gender = "female", pregnant = FALSE, lactation = FALSE)

Arguments

my_daily_food	matrix or list of matrices, where each matrix reports a daily intake. The matrix must have two columns: 1)"food" (reporting food names) and 2) "units" (reporting the number of units relative to 100 grams, e.g. 125 g -> 1.25).
food_database	character vector indicating the food database to be used. Possible values are: "USDA", "CIQUAL", "BEDCA", "STFCJ".
nutrients	character vector indicating the subset of nutrients that will be displayed. NULL indicates that all nutrients will be displayed.
age	numeric vector indicating age.
gender	character vector indicating gender (i.e. "female" or "male").
pregnant	logical constant indicating pregnancy status.
lactation	logical constant indicating lactation status.

Value

A timeseries plot displaying nutrient intake levels against time.

## Generate plots
nutrientsTimeTrend(my_daily_food = sample_diet_USDA, food_database = "USDA",
                   age = 27, gender = "female")

nutrientsTimeTrend(my_daily_food = sample_diet_USDA, food_database = "USDA",
                   nutrients = c("Calcium, Ca (mg)", "Iron, Fe (mg)"), age = 27,
                   gender = "female")
