Hello Rui,
Thanks for your kind and unrelenting help. The code works actually. I will
see what to do to sort things out. Please, accept my indebtedness.

Hello Rui,
Your patience is indeed amazing. Your script tested as shown below worked
perfectly well.
df1 <- read.table(text = "YEAR DOY HR IMF SW SSNDst f10.7
2012 215 4 5.1 371. 143-4 138.6 ", header = TRUE)
with(df1, paste(YEAR, DOY)) |> as.Date(format = "%Y %j")
df1$Date <-

Thank you Rui. I ran the following script
df1 <- read.table("solar_hour", header = TRUE)
df1$date <- as.Date(paste(df1$year, df1$hour),
format = "%Y %j",
origin = "2012-08-01-0")
df2 <- df1[c("date", "IMF", "SWS", "SSN", "Dst", "f10")]
Please run your sequence of R statements one at a time so you can tell where
the problem is. Only "run a script" after the code works one line at a time.
There are too many places where things can go wrong otherwise.
Is your file being read in properly? Is the filename correct? was the header
Thank you Rui. I ran the following script
df1 <- read.table("solar_hour", header = TRUE)
df1$date <- as.Date(paste(df1$year, df1$hour),
format = "%Y %j",

df2 <- df1[c("date", "IMF", "SWS", "SSN", "Dst", "f10")]
head(df1)
#To display all the rows
print(df2).
It gave me
- df_date2[ , -c(2, 9, 10)]
# Reorganize columns to desired locations
df_date2 <- df_date2[, c("YEAR", "M", "D", "IMF", "SW", "SSN", "Dst", "f10.7")]
# Rename "Year" to "Y"
