这个问题可能是因为字形设定不正确导致的。你可以尝试在函数中添加一个`font`参数，指定字体类型，例如：

pairs(data, lower.panel = function(x, y) {
  points(x, y, pch = 19, cex = 0.5, col = "#3C9668")
  abline(lm(y ~ x), col = "red")
}, diag.panel = function(x) {
  hist(x, col = "#D8EAF6", probability = TRUE, axes = FALSE, main = "", breaks = "FD")
}, upper.panel = function(x, y) {
  corr_text <- round(cor(x, y), 2)
  symbol_size <- abs(corr_text) * 5
  color_scale <- colorRampPalette(c("#F09576", "white", "#175A9E"))
  symbol_color <- color_scale(5 + corr_text * 5)
  symbols(1, 1, circles = symbol_size, inches = FALSE, bg = symbol_color)
  text(mean(x), mean(y), round(cor(x, y), 2), cex = 1.5, font = 2)
}, labels = c("FBD", "VC", "EO", "OF", "DP", "VC-FBD", "EO-VC", "OF-EO", "DP-OF", "DP-EO"), font.labels = list(cex = 1.5))

在`upper.panel`函数中添加了`text`函数，指定圆圈中心坐标和相关性数字，同时添加了`font`参数，指定字体类型为粗体（`font = 2`）。
