Number of Observations: 1 Let’s consider another scenario where you want to count the number of observations in an R data frame based on a specific condition using thewith()andsum()functions. sample_data<-data.frame(ID=c(1,2,3,4,5),Name=c("Alice","Bob","Charlie","David","Eva"...

Eventhough I feel bad for you but simultaneously I am cheering you on for quantifying your observations and feelings so clearly. This gives me hope. Last week 2 days before my child who is my precious one told me I am an less than a mother to them. Broke my heart. I finally decided...
If you’re a beginner, focus on the first part about why learning numbers in sequence is not good. More advanced students will gain more from the later parts and might want to skip the first one. 1. Learning to count as a beginner: Why learning numbers in sequence is bad ...

In some cases, presence data is recorded as a count of presence events in quadrat cells: each observation increments a count at its location, and a variety of modeling approaches can be used to model this count, such as the Poisson method of theGeneralized Linear Regressiontool. In other...
