sdata<-subset(data,STATE_OR_REGION & 1910_POPULATION & 1920_POPULATION & 1930_POPULATION & 1940_POPULATION & 1950_POPULATION & 1960_POPULATION & 1970_POPULATION & 1980_POPULATION & 1990_POPULATION & 2000_POPULATION & 2010_POPULATION)

these are the columns i want to include in the subset of the dataframe to plot in the graph

You can subset the data. `df1 <- data[1, 1:11]` would give you 1st row and 11 columns of the dataframe. — Ronak Shah, Jan 12 '20 at 01:42

I think this answer will show you what you want. The whole post shows a few different ways to do it but the linked response shows how to use the column names to subset.

So in your case if you want to use the column names:

sdata <- data[, c("STATE_OR_REGION","1910_POPULATION", . . . )]
