Examples

# Creates an attachment whose content is the content of this file,
# and whose name is "model.lp" (the 3 expressions are equivalent):
a <- addAttachment(file = "/home/joe/models/model.lp")
a <- addAttachment(name = "/home/joe/models/model.lp")
a <- addAttachment("/home/joe/models/model.lp")

# Creates an attachment whose content is the specified file, and
# whose name is "model.lp"
a <- addAttachment(name = "model.lp",
                   file = "/home/joe/models/model_1231.lp")

# Create an attachment whose data is stored in memory
model <- "Minimize
            obj: x + y
          Subject To
          Bounds
            3 <= x <= 17
            2 <= y
          End"
a <- addAttachment(name="model.lp",
                   data=charToRaw(model))
## Not run: 
# Submits and runs the specified model.lp:
job <- client$submitJob(addAttachment("/home/joe/models/model.lp"))

## End(Not run)
