Hello,
Thanks for the data in dput format.
If you run
str(bwchist)
you will see that what you have is a data.frame, yes, but, with columns of
class "list", not vectors.
So the first step is to make them vectors, to unlist the lists. I will do
it applying function unlist() to each of the columns. Since lapply returns
a list, I remake a data.frame. The original is kept unchanged, the new
object is bwch.
bwch <- lapply(bwchist, unlist, recursive = FALSE)
bwch <- do.call(cbind.data.frame, bwch)
str(bwch)
Now that everything is as it should, here are two ways of plotting bar
graphs.
#--- base R
x11(width = 11.5, height = 6)
old_par <- par(mar = par("mar") + c(1, 0, 0, 0))
bp <- barplot(bwch$reval, yaxt = "n", ylim = c(-1, 0.4))
axis(1, at = bp, labels = bwch$Accion, las = 2)
axis(2, at = pretty(bwch$reval))
par(old_par)
#--- package ggplot2
library(ggplot2)
x11(width = 11.5, height = 6)
ggplot(bwch, aes(factor(Accion, levels = Accion), reval)) +
geom_col() +
theme(axis.text.x = element_text(angle = 60, hjust = 1))
Hope this helps,

Hi Rasmus, Josh and Rui,
First of all many thanks in advance about your help.
The first thig is sometimes you say " you are posting in HTML and that
makes the
post unreadable as this is a plain text list" how can I put the code in
the correct way, not html (attaching in txt?)
The second about the code:
I have used this:
bwc <- cbind(bwfinal2,bwfinal)
colnames(bwc)=c("Accion","reval")
df <- matrix(unlist(bwc), nrow=nrow(bwc), byrow=F)
colnames(bwchist)=c("Accion","reval")
bwchist <-as.data.frame(bwc[order(df[,2]), ])
bwchist is the ordered cum stock returns in the year but because is a list
it is not possible to plot and histogram with x (names of stocks) and the x
axist the value of cum stocks (reval)
when I put dput(bwchist) the console says:
dput(bwchist)
structure(list(Accion = list("REE", "Enagas", "Grifols", "Ferrovial",
"Acerinox", "Naturgy", "Inditex", "Bankia", "ENCE", "Aena",

I try to make an hist or barplot but because it is a list no way to obtain
the plot.
Many thanks again for your help.
I have printed two manuals to improve my level, but if you can help me, I
would be very very gratefull.

| |
| | Please post the output of

| Hi Pedro,
|
| Another 'best practice' and polite

| another forum.
|
| I saw your post on R-SIG-Finance
| (https://stat.ethz.ch/pipermail/r-sig-finance/2020q3/014979.html),
| and started to work on a solution.
|
| I don't know how to do this in
| tidyquant, but here's how you can do
| it with quantmod:
|
| # all tickers
| tk <- c("ANA.MC", "ACS.MC", "AENA.MC", "AMS.MC", "MTS.MC", "BBVA.MC", "
SAB.MC",
| "SAN.MC", "BKT.MC", "CABK.MC", "CLNX.MC", "ENG.MC", "ENC.MC", "ELE.MC
",
| "FER.MC", "GRF.MC", "IBE.MC", "ITX.MC", "COL.MC", "IAG.MC", "MAP.MC",
| "MEL.MC", "MRL.MC", "NTGY.MC", "REE.MC", "REP.MC", "SGRE.MC", "TEF.MC
",
| "VIS.MC", "ACX.MC", "BKIA.MC", "CIE.MC", "MAS.MC", "ALM.MC", "IDR.MC
")
|
| # download them into an environment ('e')
| require(quantmod)
| getSymbols(tk, from = "2019-12-31", env = (e <- new.env()))
|
| # extract adjusted close column
| adj <- lapply(e, Ad)
| # calculate daily returns from adjusted data,
| # merge into a xts matrix, and fill NA with 0
| ret <- do.call(merge, c(lapply(adj, dailyReturn), fill = 0))
| # cumulative returns
| cumret <- cumprod(1 + ret) - 1
| # set names
| colnames(cumret) <- names(adj)
| last(cumret)
| # calculate histogram for period-to-date returns
| hist(drop(last(cumret)))
|
| I'm not sure that's the histogram
| you're looking for, but I hope it
| gives you a start toward a solution.

| Best,

Wow Josh! That's very elegant.
Myself now, I just plowed through the
original code to make it simpler, but am
at a loss as to how this histogram looks
