Draft Model of Forced Evaporation from a Water Surface, with user choice of wind function Multiplant Lake/Pond/River Version 3.104 - 2012/12/15

fewsr(file = tk_choose.files(default = "", caption =
  "Select file to open", multi = FALSE, filters =
  matrix(c("Comma-separated value file", ".csv", "MS Excel spreadsheet",
  ".xlsx", "MS Excel 97-2003 spreadsheet", ".xls"), 6, 2, byrow = TRUE)),
  sheet = 1, type = c("lake", "pond", "river"), output = c("csv",
  "xlsx", "both"))

`file`	Input file will be selected through a file dialog [.xls(x) or .csv]
`sheet`	Sheet number or sheet name for the input file
`type`	The type of surface water feature (lake, pond, river)
`output`	The output format of the resulting spreadsheet (.xlsx, .csv, or both)

spreadsheet with the output parameters and a plot of the average evaporation per month
