Hi everybody, Question: why are my dataframe and numeric variables a character? I read an excel file via readxl but my dataframe is a character, and numeric variables, eg "yi", are also a character. My excelfile is in English numeric Sometimes the dataframe was indeed a dataframe, but I do not know why it did sometimes. Thank you in advance, Roberto PS I used "guess". The problem is not solve by using "text", "numeric" etc My syntax (I think I cannot send the excel file as binary?)> library(readxl) > library(readxl) > library(metafor) > setwd("C:/docs/Work2/Statistic_Analyses/MetaQTcAD") > getwd()[1] "C:/docs/Work2/Statistic_Analyses/MetaQTcAD">> dat <- read_excel("Hedges-g_QTc MA_R05.xlsx", sheet = 2, col_names=TRUE,col_types = c("guess"))> class("dat")[1] "character"> class("yi")[1] "character">[[alternative HTML version deleted]]
class("dat") is different from class(dat), which is what you actually
want.

Hi Roberto, This often happens when there are some non-numeric characters. You would have to check it. Without more information, e.g. dput(dat), you will have to find by yourself.
