Please consider the following MWE
library(xtable)
DF <- as.data.frame(UCBAdmissions)
print(xtable(DF, align="p{0.4\textwidth}|p{0.15\textwidth} p{0.15\textwidth} p{0.15\textwidth}"), sanitize.text.function = function(x){x},
table.placement="!htp", include.rownames=FALSE,
tabular.environment='longtable',floating=FALSE)
I want to set the alignment of my longtable
like
\begin{longtable}{p{0.4\textwidth}|p{0.15\textwidth} p{0.15\textwidth} p{0.15\textwidth}}
Still when I try to pass the argument to a xtable
object I get
Warning message:
In .alignStringToVector(value) : Nonstandard alignments in align string
Error in print(xtable(DF, align = "p{0.4\textwidth}|p{0.15\textwidth} p{0.15\textwidth} p{0.15\textwidth}"), :
error in evaluating the argument 'x' in selecting a method for function 'print': Error in `align<-.xtable`(`*tmp*`, value = "p{0.4\textwidth}|p{0.15\textwidth} p{0.15\textwidth} p{0.15\textwidth}") :
"align" must have length equal to 5 ( ncol(x) + 1 )
I understand I should add the alignment for a 5th column (how?) but also I don't understand the error message. Should I sanitize the string?
I am unable to test this but I think you need to apply standard R escaping to backslashes in a string , remove the extraneous "\" and add the missing "pipe bars" (|
). Then the align<-
succeeds with only a warning:
xtb <- xtable(DF,
table.placement="!htp", include.rownames=FALSE,
tabular.environment='longtable',floating=FALSE)
align(xtb) <- "p{0.4\\textwidth}|p{0.15\\textwidth}|p{0.15\\textwidth}| p{0.15\\textwidth}"
#Warning message:
#In .alignStringToVector(value) : Nonstandard alignments in align string
print(xtb)
Or:
xtb <- xtable(DF, type="latex",
table.placement="!htp", include.rownames=FALSE,
tabular.environment='longtable',floating=FALSE, align= c("p{0.15\\textwidth}",
"p{0.4\\textwidth}", "p{0.15\\textwidth}|", "p{0.15\\textwidth}", "p{0.15\\textwidth}"
))
