R Filter Dataframe with atleast N number of non-NAs
In this tutorial, we will learn how to filter rows of a dataframe with alteast N number of non-NA column values.
Filter R Dataframe with atleast N number of non-NAs
To filter rows of a dataframe that has atleast N non-NAs, use dataframe subsetting as shown below
resultDF = mydataframe[rowSums (is.na(mydataframe[ , 0:nc ol(mydat aframe)]) )reAm, 7y4d)a,tapfr=amc(eN=A,d6a3ta, .frame(x = c(9, NA, 7, 4), y = c(4, NA, NA, 21), z = c(9, 8, NA, 74), p = c(NA, 63, NA, 2)) NA, 2)) >>mmyyddaattaaffrraammee
xx yy zzp p 1 9 4 9 NA 21 N9A4N9AN8A 63 342 N74AN21NAA7N48A 6N23A 3 7 NA NA NA 4 4 21 74 2
Now, we will filter this dataframe such that the output contains only rows with atleast 2 non-NAs.
> N = 2 > resultDF = mydataframe[rowSums (is.na(mydataframe[ , 0:nc ol(mydat aframe)]) ) resultDF
x y z p 1 9 4 9 NA 2 NA NA 8 63 4 4 21 74 2
> N = 2 > resultDF = mydataframe[rowSums(is.na(mydataframe[ , 0:ncol(mydataframe)])) resultDF
x y z p 1 9 4 9 NA 2 NA NA 8 63 4 4 21 74 2 >
Let us try with N = 3.
> N=3 > resultDF = mydataframe[rowSums (is.na(mydataframe[ , 0>:nNc=o3l(mydataframe)]) ) ncroels(umltyDdFat=afmraymdea)ta-frame[rowSums(is.na(mydataframe[ , 0:ncol(mydataframe)])) ),re]sultDF > resultDF
xx yy zzp p 141 949 24419794NNAA2 >4 4 21 74 2 >
Concluding this R Tutorial, we have learned to filter a Dataframe based on the number of non-NAs (or ofcourse NAs) in a row.
