Description
Plots the Standardized Precipitation Index of a precipitation serie.
Usage
pplot.spi(..., period = 3, distribution = "Gamma", xlab = "Months",
ylab = "SPI", ylim = c(-3,3), legend = NULL, fontsize = 10,
axis.text.color = "black", export = FALSE, export.name = "spi_plot.png",
width = 8.6, height = 7.5, units = "cm")
Arguments
period |
the number of months to be aggregated for calculating the standardized precipitation index. (Default value: 3) |
distribution |
it has no effect yet. (Default value: "Gamma") |
xlab |
the text for the x axis. (Default value: "Months") |
ylab |
the text for the y axis. (Default value: "SPI") |
ylim |
the limits of the y axis. (Default value: c(-3, 3)) |

the text vector for the legend items. If NULL the legends will be equals to the variable names. (Default value: NULL) |
fontsize |
the font size value in pt. (Default value: 10) |
axis.text.color |
the legend colors. (Default value: "black") |
export |
the logical value for defining whether the graph should be export to a file or not. (Default value: FALSE) |
export.name |
the text for defining the exported file name. It is only used if export = TRUE. (Default value: "spi_plot.png") |
width |
the number for defining the exported graph width. It is only used if export = TRUE. (Default value: 8.6) |
height |
the number for defining the exported graph height. It is only used if export = TRUE. (Default value: 7.5) |
units |
the text for defining the units of the height and width parameters. It is only used if export = TRUE. (Default value: "cm") |
... |
