我有一个包含 1000 个数据框的列表(每个都有 4 个同名的列)。我想绘制绘图并以交互方式处理它们。以下是示例(单个列表有 3 个数据框)。
# dummy data
c1 <- rnorm (40, 0.1, 0.02); c2 <- rnorm (40, 0.3, 0.01)
c3 <- rnorm (40, 0.5, 0.01); c4 <- rnorm (40, 0.7, 0.01)
c5 <- rnorm (40, 0.9, 0.03)
Yv <- 0.3 + rnorm (200, 0.05, 0.05)
# frist dataframe
var1 <- data.frame (idnames = paste ("ID", 1:200, sep = ""), Theta = round (c(c1, c2, c3, c4, c5), 2), R = round (Yv, 2), cltr = c(rep(1:5, each = 40)))
# same dummy data filled in second dataframe
var3 <- data.frame (idnames = paste ("ID", 1:200, sep = ""), Theta = round (c(c1, c2, c3, c4, c5), 2), R = round (Yv, 2), cltr = c(rep(1:5, each = 40)))
# same dummy data filled in third dataframe
var_5 <- data.frame (idnames = paste ("ID", 1:200, sep = ""), Theta = round (c(c1, c2, c3, c4, c5), 2), R = round (Yv, 2), cltr = c(rep(1:5, each = 40)))
# the list (the original list has >1000 dataframes)
mylist <- list (var1 = var1, var3 = var3, var_5 = var_5)
我想为每个数据框创建相似的图,但我需要一个一个地工作并保存并移至下一个图
# plot for var1
myd1 <- data.frame (mylist[1])
names (myd1) <- c("idnames", "Theta", "R", "cltr")
plot(myd1$Theta, myd1$R, col=myd1$cltr+1, pch = 19, main = names (mylist[1]))
exclude <- identify(myd1$Theta, myd1$R)
## left click on the points you want to exclude (right click to stop/finish)
myd1$cltr1 <- as.numeric ( myd1$cltr)+ 1
myd1$cltr1[exclude] <- 1
plot(myd1$Theta, myd1$R, col=myd1$cltr1, pch = 19, main = names (mylist[1]))
我可以对列表中的其他数据框执行相同的操作,例如 2:
myd2 <- data.frame (mylist[2])
names (myd2) <- c("idnames", "Theta", "R", "cltr")
plot(myd2$Theta, myd1$R, col=myd2$cltr+1, pch = 19, main = names (mylist[2]))
exclude <- identify(myd2$Theta, myd2$R)
## left click on the points you want to exclude (right click to stop/finish)
myd2$cltr1 <- as.numeric ( myd2$cltr)+ 1
myd2$cltr1[exclude] <- 1
plot(myd2$Theta, myd1$R, col=myd2$cltr1, pch = 19, main = names (mylist[2]))
我有一些问题:
(1)我想循环这个过程,一个图一次弹出我们,当编辑完成时,图关闭,下一个数据框的新图弹出工作等等,并继续到列表中的最后一个数据框。
(2) 是否可以在父列表中循环进程并保存对它的更改,而不是创建新的数据框。
帮助表示赞赏。
