R Tool Not Rendering Graph Correctly

Hello,

Has anyone had trouble integrating ggplot2 with the R tool? I use the following code that loops through variables and graphs them using R Studio:

for(i in variable1) {
t <- all_peril1 %>%
arrange(Variable, as.numeric(Level)) %>%
filter(Variable == i) %>%
ggplot(aes(x = as.factor(as.numeric(Level)), group = 1)) +
geom_point(aes(y=factor, color = model)) +
geom_line(aes(y = factor, group = model, color = model)) +
#geom_text(aes(y = factor, label = round(factor, digits =2)),position = position_dodge(width=.09), size = 3, vjust = -.5) +
theme(axis.text.x = element_text(angle = 90, hjust =1)) +
labs(title = "Motor Home Peril Comparison", colour="Peril",x=i,y="Factor")
out <- paste0(as.name(i), ".pdf")
ggsave(out, plot = t, device = "pdf", width = 10, height = 6, units = "in")
print(t)
}

When I run the exact same code in Alteryx's r-tool, I get the wrong x axis labels and thus, the wrong graph using the same data set: The only difference is that I wrapped the code in the AlteryxGraph statement.

AlteryxGraph(1, width=2400, height=3000, res=300)
#Insert code to plot graph here

all_peril1 <- all_peril %>% #bind rows within paraenthisis
filter(!is.na(as.numeric(Level))) %>% #filter to what level is not numeric
arrange(Variable, as.numeric(Level)) #arrange by variable and levels

variable1 <- unique(all_peril1$Variable)

for(i in variable1) {
t <- all_peril1 %>%
arrange(Variable, as.numeric(Level)) %>%
filter(Variable == i) %>%
ggplot(aes(x = as.factor(as.numeric(Level)), group = 1)) +
geom_point(aes(y=factor, color = model)) +
geom_line(aes(y = factor, group = model, color = model)) +
#geom_text(aes(y = factor, label = round(factor, digits =2)),position = position_dodge(width=.09), size = 3, vjust = -.5) +
theme(axis.text.x = element_text(angle = 90, hjust =1)) +
labs(title = "Motor Home Peril Comparison", colour="Peril",x=i,y="Factor")
#out <- paste0(as.name(i), ".pdf")
#ggsave(out, plot = t, device = "pdf", width = 10, height = 6, units = "in")
print(t)
}
#pie(c(0.12, 0.3, 0.26), col = c("purple","violetred1","green3"))
invisible(dev.off())

Does anyone have an idea why this is happening?

Hi @jbh1128d1,

What version of Alteryx Designer do you use please?

Would you be able to share a package with your workflow and data source?

I have run the following test [source: http://tutorials.iq.harvard.edu/R/Rgraphics/Rgraphics.html] but I couldn't recreate your issue.

Environment: 2018.1, R 3.3.2

same behaviour with different resolution for AlteryxGraph

In RStudio:

In Alteryx Designer:

Hi @PaulN.

I'm using Alteryx Designer version 11.7.4.37815.

I can't hand this data over but I ended up using a filter tool and picking which variables I wanted to sort in numeric order and changed those variables values to integers. Then I run the code twice. In effect, the filter tool and change to integer replaced the following code:

all_peril1 <- all_peril %>% #bind rows within paraenthisis
filter(!is.na(as.numeric(value))) %>% #filter to what level is not numeric
arrange(Variable, as.numeric(value)) #arrange by variable and levels
