问题
I have been trying to use qgraph to generate the network graph. The code is as following
Gw <- qgraph(edgeList, diag = TRUE, labels = TRUE,legend.cex = 0.3, vsize = 1,edge.color=colorLabels,legend=TRUE,asize=1)
The figure can be generated, but the R command line gives the following error message. I do not know what does the invalid color name 'background' mean.
The dput result is shown as follows,
dput(edgeList) structure(c("1", "2", "2", "3", "4", "5", "6", "7", "8", "1", "9", "10", "11", "12", "13", "14", "15", "16", "17", "18", "16", "4", "5", "7", "1", "9", "10", "19", "20", "2", "16", "21", "3", "22", "5", "23", "8", "1", "20", "2", "13", "14", "17", "14", "1", "19", "14", "2", "21", "14", "24", "1", ":499.3", "nk Transfe", "de of tran", "up(non-US ", "up(non-US ", "up(non-US ", "up(non-US ", "up(non-US ", "up(non-US ", "up(non-US ", "up(non-US ", "up(non-US ", "ine:4121", "ine:3257.4", "ine:75.2", "ine:75.2", "ine:11615.", "ine:10603", "ine:334.2", "ine:7256.8", "ine:7256.8", "ine:996.8", "ine:884.6", "ine:364.9", "ine:6360", "ine:5640.9", "ine:2729.7", "ine:5482.6", "ine:85", "ine:1474.9", "ine:700.8", "ine:2754.6", "ine:3257.4", "ine:3257.4", "ine:7307.8", "ine:18560.", "ine:85.1", "ine:364.8", ":700.1", ":5317", "l:4258.9", "l:4258.9", "l:1637.6", "l:1637.6", "l:46.4", "l:3938.5", "l:3938.5", "l:2800.4", "l:2715.1", "l:2715.1", "l:12708.2", "l:1042", ":499.3", "nk Transfe", "de of tran", "up(non-US ", "up(non-US ", "up(non-US ", "up(non-US ", "up(non-US ", "up(non-US ", "up(non-US ", "up(non-US ", "up(non-US ", "ine:4121", "ine:3257.4", "ine:75.2", "ine:75.2", "ine:11615.", "ine:10603", "ine:334.2", "ine:7256.8", "ine:7256.8", "ine:996.8", "ine:884.6", "ine:364.9", "ine:6360", "ine:5640.9", "ine:2729.7", "ine:5482.6", "ine:85", "ine:1474.9", "ine:700.8", "ine:2754.6", "ine:3257.4", "ine:3257.4", "ine:7307.8", "ine:18560.", "ine:85.1", "ine:364.8", ":700.1", ":5317", "l:4258.9", "l:4258.9", "l:1637.6", "l:1637.6", "l:46.4", "l:3938.5", "l:3938.5", "l:2800.4", "l:2715.1", "l:2715.1", "l:12708.2", "l:1042", "25", "1", "1", "26", "27", "28", "29", "30", "31", "25", "32", "33", "4", "4", "3", "3", "5", "5", "7", "6", "6", "27", "28", "30", "25", "32", "33", "9", "8", "1", "1", "10", "12", "12", "16", "16", "16", "16", "8", "1", "3", "3", "7", "7", "25", "9", "9", "1", "10", "10", "14", "14"), .Dim = c(104L, 2L), .Dimnames = list(NULL, c("newsendId", "newtoId")))
The generated figure is as follows. I used the following command to generate it
Gw <- qgraph(edgeList, layout = "spring", diag = FALSE, labels = TRUE, cut = NULL, edge.color = "red",legend.cex = 0.5, vsize = 8)
回答1:
Which nodes are problems? With your data and code you can modify label.cex. There are other variations of the arguments for the label and legend sizes
. Here is one version, with the color blue.
library(qgraph)
Gw <- qgraph(edgeList, layout = "spring", diag = FALSE, labels = TRUE, cut = NULL, edge.color = "red", legend.cex = 0.3, vsize = 4, label.cex = 0.3, label.color = "blue")
Gw
