R help - May 2023 - [External] Error in percentage stacked barplot

Dear all,?
I am trying to plot the following table in stacked barplot in percentages and
also horizontal.
Component? ? ? Sample 1? ? ? Sample 2? ? ? Sample 3CaO????????????????? ?
45????????????? ? 52????????????? ? 48SiO2????????????????? ?25????????????? ?
22????????????? ? 18Al2O3?????????????????15????????????? ? 11????????????? ?
14TiO2? ? ? ? ? ? ? ? ? ? ?6? ? ? ? ? ? ? ? ? 5? ? ? ? ? ? ? ? 6? ?
??Na2O????????????????? ? 5????????????????? 4????????????? ? 5CuO? ? ? ? ? ? ?
? ? ? ? 3? ? ? ? ? ? ? ? ? 3? ? ? ? ? ? ? ? 5? ? ? ?
?Cl?????????????????????????1????????????????? 3? ? ? ? ? ? ? ? 4
When I tried the following functionbarplot(data,
+         main = "Stacked bar chart",
+         sub = "Subtitle",
+         xlab = "X-lab",
+         ylab = "Y-lab",
+         axes = TRUE, horiz = TRUE)
I got the following error
Error in barplot.default(hellisheidi, main = "Stacked bar chart", sub
= "Subtitle",  :
  'height' must be a vector or a matrix
I also tried barplot(as.matrix(hellisheidi)) but what I was getting was the
three stacked columns for Samples 1, 2 and 3 but I was getting an empty column
for Component, instead of being the variable in the Samples.


I was hoping if you could help me on that. 
Thank you very much in advance. 
Kind regards,Maria
