ggtrendline outputs

[ask4jubad]

Using the ggtrendline within a for loop does not produce an output except with other I/O methods like plot, view, show, print.

Dear ask4jubad,

Thanks for your comment on this issue.

As you mentioned, plot(), show(), and print() were suggested for a loop, but not View().

• For a loop, your codes worked very well:

for (i in c("line2P", "line3P", "log2P", "exp2P", "exp3P", "power2P", "power3P")){
p <- ggtrendline(x, y, model = i, ...)
print(p)
}
# or show(p)
# or plot(p)

• If you want to add geom_point() together with ggtrendline() for a loop, try it as follows:

for (i in c("line2P", "line3P", "log2P", "exp2P", "exp3P", "power2P", "power3P")){
p <- ggtrendline(x, y, model = i, ...) + geom_point(aes(x, y),  color = "blue", shape = 1, size = 3)
print(p)
}
# or show(p)
# or plot(p)
# Pay special attention to the position of each left and right parenthesis above.

Best regards
