Return row of Data Frame based on value in a column - R

Question

My R data.frame df looks like:

     Name     Amount
1    \"A\"      150
2    \"B\"      120
3    \"C\"      \"NA\"
4    \"D\"      160
.
.
.
         


        

Answer 1

Use which.min:

df <- data.frame(Name=c('A','B','C','D'), Amount=c(150,120,175,160))
df[which.min(df$Amount),]

> df[which.min(df$Amount),]
  Name Amount
2    B    120

From the help docs:

Determines the location, i.e., index of the (first) minimum or maximum of a numeric (or logical) vector.
