Varietal database of lentil in Nepal

This one is my effort to compose an updated database on the current situation of lentil germplasm in Nepal. I’ve managed to list out the varieties that have been made available so far (either through release or registration process).

Tidyverse and tidbits

Ideas surrounding tidy evaluation quote() and eval() Why quote at-all Resolved messy data with tidy evaluation List behavior Using pmap to perform list operations inside a dataframe Apply a function to certain columns only, by rows Do any arbitrary operation Using dplyr functions inside your own functions Effiecient ways to operate on list Binds each element as row but third element is list Produces rowbinding for dataframe but doesn’t work with list elements Tibble and map data to list column in isolation Modeling, exploration, summary extraction and visualization examples using dplyr verbs.

Flowering phenology of Rice genotypes in irrigated tropical condition of Nepal

Dhangadhi of Kailali, Nepal remains relatively hotter during summer season with respect to average condition of terai agro-ecology. A regime of high day temperature with bright sunshine and cool night temperature along with plenty of seasonal rain during larger part of rice growing season favors good growth of rice crop in the region.

Memorize the date? Don't need to, use lubridate

My sufferance Time and again, I’ve suffered due to my humanistic limitations of memorizing things promptly. I suck at remembering stuffs, dates particularly. So, In this blog trip (Oh! this is a trip btw, because I don’t forsee myself surpassing my memory limitations any sooner than death), I will be stating if not rambing on some lifesaving tricks of picking up pieces of your faulty brain.

How to quickly view object size

Background In object oriented programming, everything is an object – even functions. One of the defining features of OOP, and especially that of R, is that all objects are characterized by their classes. Each class on the other hand have their repective attributes and methods defined.

Diallel cross: A case study of mating designs

Mating designs Introduction Mating designs allow for partitioning of phenotypic effects – as due to genotype, environment or interacting effects among genes and alleles. Using one or more of these mating schemes, identification of heterotic groups, estimation of general and specific combining abilities and testing of environmental interactions could be done.

Stability analysis: how to guide

Meaning of stability Introduction Principles of Biplot analysis Biplot and its Inner-product Property Singular value decomposition and partitioning Column-metric preserving and associated interpretations Row-metric preserving and associated interpretations Data centering prior to SVD Data scaling prior to SVD Four questions to be asked before trying to interpret a biplot Simplest case of biplot analysis Multienvironment trial data AMMI Analysis References Meaning of stability Comparison of treatments may also imply cross comparison of their stability across multiple environments, especially when a study constitutes a series of trials that are each conducted at different locations and/or at different periods in time (henceforth referred to as MET; Multi-Environment Trial).
