    You may try something along these lines:

    # read data.frame with read.csv; here, we create an example by hand:
    df = data.frame(
    ? ? ? ? ? ? ? ? a = 1:3, b = 3:1, geom = c("LINESTRING(0 0, 1 1)",
    "LINESTRING(1 1,2
    2)", "LINESTRING(5 5,6 6)")
    )

    library(sf)
    sf = st_sf(df, geom = st_as_sfc(df$geom))
    sf
