R Language Data frames Subsetting Rows by Column Values
Example
Built in functions can subset rows with columns that meet conditions.
df <- data.frame(item = c(1:10),
price_Elasticity = c(-0.57667, 0.03205, -0.04904, 0.10342, 0.04029,
0.0742, 0.1669, 0.0313, 0.22204, 0.06158),
total_Margin = c(-145062, 98671, 20576, -56382, 207623, 43463, 1235,
34521, 146553, -74516))
To find rows with price_Elasticity > 0:
df[df$price_Elasticity > 0, ]
item price_Elasticity total_Margin
2 2 0.03205 98671
4 4 0.10342 -56382
5 5 0.04029 207623
6 6 0.07420 43463
7 7 0.16690 1235
8 8 0.03130 34521
9 9 0.22204 146553
10 10 0.06158 -74516
subset based on price_Elasticity > 0 and total_Margin > 0:
df[df$price_Elasticity > 0 & df$total_Margin > 0, ]
item price_Elasticity total_Margin
2 2 0.03205 98671
5 5 0.04029 207623
6 6 0.07420 43463
7 7 0.16690 1235
8 8 0.03130 34521
9 9 0.22204 146553
