R: Summarized magnitude distribution

mag.distr

R Documentation

Summarized magnitude distribution

Description

Table and graphical representation of summarized magnitude distribution for a given magnitude dataset, specified meteor shower and time period.

Usage

mag.distr(data,year,month.beg,month.end=month.beg,day.beg,day.end=day.beg,
time.beg=0,time.end=2359,shw)

Arguments

`data`	data frame consisting of visual meteor magnitude data.
`year`	numeric vector of length 4 specifying year.
`month.beg`	numeric vector specifying the beginning month.
`month.end`	numeric vector specifying the ending month. By default, `month.end` is set to be equal to `month.beg`.
`day.beg`	numeric vector specifying the beginning day.
`day.end`	numeric vector specifying the ending day. By default, `day.end` is set to be equal to `day.beg`.
`time.beg`	numeric vector (0-2359) specifying lower boundary of time in hours and minutes, corresponding to `day.beg`. By default, `time.beg` is set to be equal to 0.
`time.end`	numeric vector(0-2359) specifying upper boundary of time in hours and minutes, corresponding to `day.end`. By default, `time.end` is set to be equal to 2359.
`shw`	character string consisting of three capital letters which represent meteor shower code.

Details

Summarized magnitude distribution is formed by summing frequencies of all observers for each magnitude value.

Value

Table and plot of summarized magnitude distribution consisting of histogram and boxplot.

The histogram cells are intervals of length 1, with midpoints at magnitude values.

Examples

## select data for observations of Perseids, period 12-14th August  2007 
## and make graphics of magnitude distribution
data(magn07)
magnPer<-filter(magn07,shw="PER", year=2007, month.beg=8, day.beg=12, day.end=14)
mag.distr(magnPer,year=2007, month.beg=8, day.beg=12, day.end=14, shw="PER")
