lfstat's Introduction

lfstat

The "Manual on Low-flow Estimation and Prediction", published by the World Meteorological Organisation (WMO), gives a comprehensive summary on how to analyse stream flow data focusing on low-flows. This packages provides functions to compute the described statistics and produces plots similar to the ones in the manual.

There is also an R-Commander Plugin "RcmdrPlugin.lfstat" which provides a graphical user interface for a subset of the functionality provided by lfstat.

lfstat's Issues

Multiple input files

Dear Tobias and all,

I found the package very useful and wanted to apply for multiple files about 10000 points available in NetCDF in a way as a loop. like read all files in a directory and compute certain tasks such as droughts find_droughts(ray) and save it into CSV.

Best regards,

Solomon

Error when using evfit, evqualtile or ev_return_Period

Hello,

I am a beginner user in R and I am hoping you can help.

I am using R R-3.4.2 with R studio1.1.383. I am attempting to learn the lfstats package and I get the following error 1.1.383 when trying to use evfit, evqualtile or ev_return_Period.

Error in samlmu(xx) : object 'RegSym_samlm' not found

The issue seems to be with the samlmu command, as the samlmu.s seems to work fine in the lmoments package. Id there a way of correcting the error or using the samlmu.s for the evfit command ?

Forgive my ignorance, my skills are very basic at this stage any help you can provide will be appreciated.

Best Regards,

R

Day, month, year data type warning

The package allows you to create an lfobj as long as you have day, month, and year columns, but it doesn't check for the data type. If you happen to create an lfobj with those columns as characters instead of as numeric (easy to do if you're using format() to convert from a date field), some functions will work, but others (hydrograph()) will not.

Maybe a warning on import to convert these fields to numeric? Or a check & autoconvert on import?

package ‘Ifstats’ is not available (for R version 4.0.2)

Hi! I need to use the Ifstats package, but even though I have just installed Rtools, I receive this error message:

install.packages("Ifstats", type = "source")
Installing package into ‘C:/Users/raiza/OneDrive/Documentos/R/win-library/4.0’
(as ‘lib’ is unspecified)
Warning in install.packages :
package ‘Ifstats’ is not available (for R version 4.0.2)

Then, I installed the newest version of both R and Rstudio, and doesn't work neither:
install.packages("Ifstats", type = "source")
Installing package into ‘C:/Users/raiza/OneDrive/Documentos/R/win-library/4.1’
(as ‘lib’ is unspecified)
Warning in install.packages :
package ‘Ifstats’ is not available for this version of R

A version of this package for your version of R might be available elsewhere,
see the ideas at
https://cran.r-project.org/doc/manuals/r-patched/R-admin.html#Installing-packages

What should I do?
Is there any new version of Ifstats to use lately?
