convert a row of a data frame to a simple vector in R

Question

I have a huge data frame from which I only select a couple of rows. Then I remove some of the columns based on a condition. let us say that I choose row 4460 as shown bellow

Answer 1

Example from mtcars data

mydata<-mtcars
k<-mydata[1,]
          mpg cyl disp  hp drat   wt  qsec vs am gear carb
Mazda RX4  21   6  160 110  3.9 2.62 16.46  0  1    4    4
names(k)<-NULL

unlist(c(k))
 [1]  21.00   6.00 160.00 110.00   3.90   2.62  16.46   0.00   1.00   4.00   4.00

Updated as per @Ananda: unlist(mydata[1, ], use.names = FALSE)
