Question

我绘制度数分布图并在其上拟合幂律，但是我不想拟合幂律，而是想在图的中点绘制平滑曲线。所以我需要帮助，如何在度数分布上拟合平滑的曲线？我的代码和图表如下。代码：

rm(list=ls())
options(max.print = 10000000)
library(igraph)

Binr<- read.delim("E:/M.Tech 3rd         sem/Thesis/Dataset/BINARY_PROTEIN_PROTEIN_INTERACTIONS.txt", na.strings="-",
              header=F, comment.char = "" , fill = TRUE , sep = "\t" )
Binrppi <- Binr[complete.cases(Binr),]
d_f <- data.frame(Binrppi$V1 , Binrppi$V4);d_f
lvl <- d_f[as.character(d_f[,1])!= as.character(d_f[,2]),];lvl
g <- graph.data.frame(lvl,directed = FALSE)
d <- degree(g)
degree <- sort(d, decreasing = TRUE)
dd <- degree.distribution(g, cumulative = FALSE)
degree <- 1:max(d);degree
probability <- dd[-1] ; probability
nonzero.position = which(probability != 0)
probability = probability[nonzero.position]
degree = degree[nonzero.position];degree
reg = lm(log(probability) ~ log(degree)) ; reg
cozf = coef(reg);cozf
summary(reg)
alpha = -cozf[[2]]; alpha
R.square = summary(reg)$r.squared
R.square
lo <- loess(degree ~ probability );lo
plot(probability ~ degree, log = "xy", xlab = "Degree", ylab = "Probability (log)", 
 col = "blue", main = "Degree Distribution")
xl <- seq(min(probability),max(probability), (max(probability) -     min(probability))/1000); xl
lines(xl, predict(lo,xl), col='red', lwd=2)

在这个情节中，我想要一个中间点的平滑曲线，如从2度到50度我的数据集太大了，这就是我无法在此处上传的原因。其PPI数据集。

感谢您提前提供任何帮助。
