I know the library(rms)
# Data
data(pbc)
d <- pbc
rm(pbc)
d$status <- ifelse(d$status != 0, 1, 0)
dd = datadist(d)
options(datadist='dd')
f <- cph(Surv(time, status) ~ rcs(age, 4), data=d)
p <- Predict(f, fun=exp)
df <- data.frame(age=p$age, yhat=p$yhat, lower=p$lower, upper=p$upper)
# X-axis
breaks <- boxplot.stats(p[,"age"])$stats
# Main plot
MP <- ggplot(data=df, aes(x=age, y=yhat)) + geom_line(size=1) +
geom_ribbon(data=df, aes(ymin=lower, ymax=upper), alpha=0.5, linetype=0, fill='#FFC000') +
theme_bw() +
scale_x_continuous(breaks=breaks) +
xlab("Age") +
ylab("Hazard Ratio") +
theme(axis.line = element_line(color='black', size=1),
axis.ticks = element_line(color='black', size=1),
panel.grid.minor = element_blank())
# Boxplot
BP <- ggplot(data=df, aes(x=factor(1), y=age)) +
geom_boxplot(width = 1, outlier.shape=NA, size=1) +
geom_jitter(position = position_jitter(width = .3), size = 1) +
scale_y_continuous(breaks=breaks) +
coord_flip() +
theme_bw() +
theme(panel.border=element_blank(),
panel.grid=element_blank())
#### Set up the grobs and gtables here
library(gtable)
library(grid)
h = 1/15 # height of boxplot panel relative to main plot panel
# Get ggplot grobs
gMP = ggplotGrob(MP)
BPg = ggplotGrob(BP)
BPg = gtable_filter(BPg, "panel") # from the boxplot, extract the panel only
# In the main plot, get position of panel in the layout
pos = gMP$layout[gMP$layout$name == "panel", c('t', 'l')]
# In main plot, set height for boxplot
gMP$heights[pos$t-2] = unit(h, "null")
# Add boxplot to main plot
gMP = gtable_add_grob(gMP, BPg, t=pos$t-2, l=pos$l)
# Add small space
gMP$heights[pos$t-1] = unit(5, "pt")
# Draw it
grid.newpage()
grid.draw(gMP)
command, but I am wanting to search for a substring such as "tack" in all text files in a directory, that would match "stackover". In my project I am trying to find where the number 44260 is located but I am pretty sure it in as a parameter for a function, and I can't find it.

您正在使用grep的非默认格式。只需搜索一种模式，您根本不需要使用-e。将路径放在查询的 end 处。这与您的有问题的查询相同：
grep -rnw "sometext" .
-w标志仅匹配完整单词。它有效地将您的查询sometext更改为\bsometext\b（其中\b是一个分词符号）。正如@melpomene在评论中指出的那样，只需删除-w，您就可以匹配子字符串：
grep -rn "sometext" .
