Missing of edge attributes in networkDynamic

[LettieWyq]

Hi,
I encountered a problem while preparing the dynamic network list.
I was trying to fit a TERGM model with both vertex attributes and edge attributes(value).
I firstly constructed a list of networks with 4 periods.
SpNetList <- list(Sp2019,Sp2020,Sp2021,Sp2022)
The attributes were all correctly specified in the list.

Vertex attribute names:
CPI FINDEV GDPPC GGDP vertex.names
Edge attribute names:
FIN TRA

However, when I transformed the SpNetlist into networkDynamic, the edge attributes were missing (both were time-varying matrix):
SpDy <- networkDynamic(network.list = SpNetList)

Vertex attribute names:
active CPI FINDEV GDPPC GGDP vertex.names
Edge attribute names:
active

Very much appreciate,
Yuqing W

Thank you for reaching out. Can you provide a reprex?

Yes! I omit the process of importing data, here is how I set attributes of the following networks:

SpNetList <- list(Sp2019,Sp2020,Sp2021,Sp2022)

vertex attributes

for(i in 1:length(SpNetList)){
for(feature in colnames(GGDP)){
SpNetList[[i]] <- set.vertex.attribute(SpNetList[[i]], "GGDP", GGDP[, i])
}
for(feature in colnames(GDPPC)){
SpNetList[[i]] <- set.vertex.attribute(SpNetList[[i]], "GDPPC", GDPPC[, i])
}
for(feature in colnames(CPI)){
SpNetList[[i]] <- set.vertex.attribute(SpNetList[[i]], "CPI", CPI[, i])
}
}

edge attributes

SpNetList <- lapply(1:length(SpNetList), function(i) {
set.edge.value(SpNetList[[i]], "TRA", value = TRAlist[[i]])
})

SpNetList <- lapply(1:length(SpNetList), function(i) {
set.edge.value(SpNetList[[i]], "FIN", value = FINlist[[i]])
})

network dynamic

SpDy <- networkDynamic(network.list = SpNetList)
SpDy

Could it be the problem that edge attributes were time-varying in my context?
