Running the
net <- as.static.tnet(lnet[lnet[,"t"]<as.POSIXlt("2004-06-30 07:00:00"),])
Command returns a
Error in as.static.tnet(lnet[lnet[, "t"] < as.POSIXlt("2004-06-30 07:00:00"), :
object 'net' not found
Do you have any thoughts?
Thanks for all your help/publishing!

Hi Jon,
The net parameter is the network object. tnet examples assume that the object is called net; however, you can name it anything as long as you update the references to it in the code.
Best,
Tore

Ah. Thanks

When I ran:
net <- as.static.tnet(lnet[lnet[,"t"]<as.POSIXlt("2004-06-30 07:00:00"),])
I got the error:
Error in as.tnet(net, type = "longitudinal tnet") :
Type of network not recognised

Hi Eseosa,
This is due to your network object, lnet, not conforming to the tnet standard. Have a look here: https://toreopsahl.com/tnet/software/longitudinal-data-structure/
If this doesn’t help, email me your code and data. Then I will have a look at it for you.

Hello Tore, when I try to create a static network I get this error:
Error in data.frame(ld[index, c(“i”, “j”)], w = 0) :
arguments imply differing number of rows: 0, 1
I’ve run as.tnet(net, type =”longitudinal tnet”) without getting errors. Googling the error says that missing values can cause it but there are none in my data. Any suggestions?
Thank you!

Jonathan,
I’m not entirely what brings about this error. If you email me the code and data you have, I’ll have a look.

Thanks for your quick reply! I’m guessing it has something to do with how I structured my data table. I actually built longitudinal data from static networks anyway so it’s not too much of a problem. Thank you for making tnet!
