Errors for osrmTrip

[HunnicuttP]

Hello,

When running osrmTrip, I am receiving two errors that I am having difficulty interpreting.

The first is:
"OSRM returned an error:
Error: "

The second is:
"OSRM returned an error:
Error: Unable to parse: GEOMETRYCOLLECTION(LINESTRING"...(followed by coordinate pairs)
"GEOS reported: "IllegalArgumentException: point array must contain 0 or >1 elements"

Any help interpreting these errors would be much appreciated.

Can you provide a reproducible example leading to this error + the output of sessionInfo() please?

Data is attached.
replication_PH.csv.zip

The following should produce the blank error:
df <- read.csv([data))
trip <- osrmTrip(df[c(81:306),])

The following should produce the "unable to parse" error:
df <- read.csv(data)
trip <- osrmTrip(df[c(1:80),])

Output from session info:
`sessionInfo()

Many thanks.

Sorry for the late reply.
The "blank error" is due to the fact that the public OSRM API does not allow trips with more than 100 locations. I've just added a more informative message. To use more than 100 locations you could use your own instance of OSRM and set the --max-trip-size option to a higher value.

The "unable to parse" error was due to a bug in the package. The bug is corrected and the current dev version should work (use devtools::install_github("rCarto/osrm")
