How to draw a directed network graph with texts on both sides of edges in R (via iGraph, network or some other package)? -


how draw directed network graph texts on both sides of edges in r (via igraph, network or other package)?

directed network graph texts on both sides of edges

variables (in vector autoregressive model (var)) in nodes.

the granger causalities (p values of f statistics) on both sides of edges. put p values beginning of each arrow. draw near-significant causalities added emphasize.

i not figure out how such network diagram via igraph or network package or else.

you can use edge.label , vertex.label options together.

library(igraph) el <- data.frame(sender = c("lnbist1f","lnbist1f","lnbist1f",                             "kur1f","kur1f","kur1f",                             "lnaltin","lnaltin","lnaltin",                             "mfaiz1f","mfaiz1f","mfaiz1f"),                  receiver = c("mfaiz1f","lnaltin","kur1f",                               "lnbist1f","lnaltin","mfaiz1f",                               "mfaiz1f","lnbist1f","kur1f",                               "lnbist1f","lnaltin","kur1f"),                  pval = c(0.5,0.6,0.1, #i typed random p-vals here                           0.45,0.88,0.24,                           0.12,0.51,0.99,                           0.001,0.056,0.123)                  ) arrows = c(2,1,0,0,1,1,1,0,0,2,1,1) el <- as.matrix(el) g <- graph_from_edgelist(el[,1:2], directed = t) coordinates <- matrix(c(4, 4, 1, 1, 4, -2,7,1), nrow = 4, byrow=true) plot(g, edge.label=el[,3],       vertex.shape="crectangle",       vertex.size=45,      edge.arrow.mode=arrows,      layout = coordinates)

the edge.arrow.mode lets control arrowheads. can move edge labels around edge.label.y , edge.label.x options.

python - How to insert QWidgets in the middle of a Layout? -

Image
i'm using qt framework build graphical user interface. use qgridlayout position qwidgets neatly. gui looks this: my application regularly adds new widgets gui @ runtime. these new widgets not added @ end of qlayout, somewhere in middle. the procedure bit cumbersome. applied on figure above, need take out widg_c , widg_d , ... qgridlayout. next, add widg_x and widg_y , , put other widgets again. how remove widgets qgridlayout: for in reversed(range(mygridlayout.count())): self.itemat(i).widget().setparent(none) ### as long you're dealing small amount of widgets, procedure not disaster. in application display lot of small widgets - perhaps 50 or more! application freezes second while procedure ongoing, annoying user. there way insert widgets somewhere in qlayout, without need take out other widgets? edit: apparently solution qvboxlayout simple. use function insertwidget(..) instead of addwidget(..) . docs can found link: http://doc.qt.io/qt-5/qboxlayou
