Hello,
Something like this?
rep(df2$load, table(df1$plot.id))
Hope this helps,

I have two dataframes (df) that share a column header ("plot.id"). In the
1st df, "plot.id" records are repeated a variable number of times based on
the number of trees monitored within each plot. The 2nd df only has a
single record for each "plot.id", and contains a variable named "load" that
is collected at the plot-level and is only listed once per plot record.
*OBJECTIVE:* I need to repeat the "load" values from the 2nd df based on
how many times "plot.id" is repeated in the 1st df (all plots are repeated
a different number of times). My example dfs are below:
************************************************************************************************
df1 <- data.frame(plot.id = rep(c("plot1", "plot2", "plot3"),
c(3,2,5)),
tree.tag = c(111,112,113,222,223,333,334,335,336,337))
df2 <- data.frame(plot.id = c("plot1", "plot2", "plot3"), load=c(17,
6, 24))
************************************************************************************************
I have gotten close to solving this, but alas I'm on day 2 of
problem-shooting and can't get it! Thanks for any help you might provide.
