Marta,
Option 1) using CreateSegments() seems to do what you want. Why don't
you simply use rgeos::over() or rgeos::gTouches() between your old and
new SLDFs to match the index positions of your old attributes to your
new segments?

Hi all,
I am working with a large datasets of boat positions, and based on this
points I created a SpatialLinesDataFrame. Now, I would like to
split/divide SpatialLinesDataframe
into n segments of 10km and keep the attributes. So far, I have tried
multiple things:
1. The function from this website: http://rstudio-pubs-static.s3.
amazonaws.com/10685_1f7266d60db7432486517a111c76ac8b.html. The problem with
it is that the function cuts the lines in segments of 10km but it is not
possible to get the attributes.
2. I have also tried the function from this website:
http://stackoverflow.com/questions/38700246/how-do-i-split-divide-polyline-
shapefiles-into-equally-length-smaller-segments. The problem is that do not
cut the segments in 10km, and it seems to cut the segments with random
lengths.
3. On the follwoing website: http://r-sig-geo.2731867.n2.
nabble.com/split-divide-SpatialLines-sp-into-n-segments-td7583234.html#
a7583629 propose to divide lines by segments but do not specify how it is
possible to do in based on the length of the segment.
Is there any function to do this in R? Or does somebody know the solution
for that?
My data looks like this:
#Script:
path_data <- "C:/R/"
mergedDF_1_DF_short<- shapefile(path_data,"mergedDF_1_DF_short")
