Insert vector in DataFrame

I have a DataFrame Df => dim(Df) = 3243 679

I would like to change a part of my dataframe for exemple:

Df[50:100,1] = c(...)

with c(...) corresponding to a vector of 50 elements.

Is there a better way to do it because it doesn't work

Error in `[<-.data.frame`(`*tmp*`, 50:100, 1, value = c("27.4349976",  : 
  replacement has 50 rows, data has 3243

Note that your vector to be inserted has fewer elements than necessary. 50: 100 are 51 elements.

set.seed(1)
df <- data.frame(a = rnorm(n = 1000),
                 b = rnorm(n = 1000),
                 c = rnorm(n = 1000))

insert <- c(runif(n = 51))

df[50:100,1] <- insert
