Hi!
I am also learning, but I want try to help. I often use for-loop in R. I
think that it could be due to dimensions of CPM, not the structure of the
loop.
What kind of error message do you get? Is it: ?incorrect number of
dimensions?? What happens if you substitute in the end instead of CPM[i,1]
this:

paste("C:/MONOGRAPHIE/Resultats/Evolution Tmoy_",CPM[i],".png",sep="")

*Aihe: *[R] "for" loop does not work with my plot_ly command
Hi everyone,
I am new to R programming, and I am having difficulties modifying an R
script to introduce the "for" loop in the code.
While searching I found that this issue has already been raised, but I did
not know what to do to fix mine !
*The code that works (without for command):*
CPM <- read.table("FicConfig/CPM.txt" , header = TRUE, sep = "\t" , dec =
",", skip = 0)
# The CPM.txt file containe 1 line
......................................................................
......................................................................
options(viewer = NULL)
plot_ly() %>%
htmlwidgets::onRender(
"function(el, x) {
var gd = document.getElementById(el.id);
Plotly.downloadImage(gd, {format: 'png', width: 1000, height: 700,
filename: 'AnomalieRR_EcartTmoy'});
}"
)%>%
add_trace(x =TAnn[ ,3], y = TAnn[ ,5], name = "Normale mensuelle de
Tmax(en ?C)",type = 'scatter', mode = 'markers', marker = list(size = T,
symbol = 'circle', color = ~TAnn[ ,5], line = list(width= 2, color = cl)))
%>%
add_annotations(text = TAnn[ ,1], x= TAnn[ ,3], y = TAnn[ ,5], font =
list(color = "white", size = 14), showarrow = FALSE)%>%
layout(title = paste("Combinaison anomalie relative annuelle des
pr?cipitations et ?cart annuel ? la normale de la temp?rature moyenne ?
",CPM[1,1],sep =""),
xaxis = list(title = "Anomalie relative des pr?cipitations
annuelles(en %)", tickangle = 20 ,titlefont = list(color= "blue", size= 14
, family = 'Arial'), tickfont = list(color = "blue", size = 14)),
yaxis = list(title = "Ecart ? la normale de la temp?rature moyenne
